Steal Divinity

# How it works

«Steal Divinity» is a magic skill used on a single player: range 600, cast time 1.2 seconds, cooldown 15 seconds. It does not work on monsters, servitors and pets.

1. The skill takes the target's latest buffs - as many as its level has attempts: from 3 on the first level to 7 on the fifth.
2. A separate roll is made for each of them. Every effect has its own chance.
3. An effect whose roll succeeded disappears from the target and appears on the thief with the same remaining time.
4. A failed roll uses up the attempt: the skill does not go further down the list to make up the full number.
5. If not a single roll succeeds, one random effect out of those that were attempted is taken anyway. A use is empty only against a target that has nothing to steal.

Skill levels

# Which effects can be stolen

The attempts go from the end of the target's effect list: first songs and dances, starting with the ones applied last, then the other effects, also from the last. An effect applied on top of the others will be first in line.

Not stolen and do not take an attempt:

1. hero skills: «Heroic Miracle» , «Heroic Berserker» , «Heroic Valor» ;
2. toggle skills and transformations;
3. debuffs;
4. effects that trigger on their own by chance.

# Chance to steal one effect

The chance is calculated in two steps.

Step 1, by levels: 5 + (skill level - effect level) x 2 + (thief's level - target's level) x 2. The result is not below 45 and not above 75.

Step 2, resistance: result of step 1 x (1 - target's resistance / 100). The final chance is not below 25% and not above 75%.

1. Skill level - 55 / 60 / 64 / 68 / 72 on skill levels one through five.
2. Effect level - the level of the skill that gave the effect; usually it is the character level at which the skill is learned. The «older» the effect, the harder it is to steal, but without resistance the chance does not go below 45%.
3. Character level difference: every level of difference between the thief and the target shifts the result of step 1 by 2 points.
4. The target's resistance to buff removal lowers the chance: resistance 30 leaves 70% of it. Resistance of 45 and above brings the chance against strong effects down to the lower limit of 25%. Vulnerability, on the contrary, increases the chance.
5. The thief's M. Atk. and the target's M. Def. do not affect the chance.

Step-by-step calculation, level 5 skill

Case	Step 1: by levels	Step 2: resistance	Chance
Level 40 effect, thief and target level 85, no resistance	5 + (72 - 40) x 2 + 0 = 69	69	69%
The same effect, target under «Arcane Protection»	69	69 x (1 - 30 / 100) = 48.3	48.3%
Level 30 effect, no resistance	5 + (72 - 30) x 2 = 89, upper limit 75	75	75%
Level 81 effect (pet song), no resistance	5 + (72 - 81) x 2 = -13, lower limit 45	45	45%
The same effect, target under «Arcane Protection»	45	45 x (1 - 30 / 100) = 31.5	31.5%
The same effect, target under «Lionheart»	45	45 x (1 - 40 / 100) = 27	27%
The same effect, target under «Arcane Protection» and «Lionheart»	45	45 x (1 - 70 / 100) = 13.5	25% (lower limit)
Level 40 effect, target under «Touch of Life»	69	69 x (1 - 100 / 100) = 0	25% (lower limit)
Level 81 effect, «Arcane Chaos» on the target	45	45 x (1 + 30 / 100) = 58.5	58.5%
Level 40 effect, thief 85, target 80	5 + 64 + (85 - 80) x 2 = 79, upper limit 75	75	75%
Level 40 effect, thief 80, target 85	5 + 64 + (80 - 85) x 2 = 59	59	59%

Chance by effect level and target's resistance (level 5 skill, thief and target of the same level)

# Chance against common effects

The chance to steal a specific effect with the level 5 skill when the thief and the target are of the same level. The effect level is taken from the skill data.

# How to protect yourself from the steal: examples

Only resistance to buff removal protects from the steal. There are three ways.

1. Keep an effect with such resistance on yourself. One effect of 30 or 40 is enough to lose 1-1.5 effects fewer; from 45 and above the chance against each effect is already at the lower limit of 25%, and more resistance adds nothing.
2. Combine two effects with resistance. Identical effects do not stack: «Arcane Protection» , «Pet Arcane Protection» , «Chant of Spirit» and «Pa'agrio's Emblem» take one slot and together give the same 30. Different ones stack: «Arcane Protection» and «Lionheart» make 70.
3. Apply last what you do not mind losing. The steal goes through the latest songs and dances, so the song refreshed last is the first to be attempted, and the effects from the start of the list are never reached.

Grand Boss jewelry does not protect from stealing: none of the pieces has protection from removal - «Earring of Antharas» , «Necklace of Valakas» , «Ring of Baium» , «Earring of Zaken» , «Ring of Queen Ant» , «Earring of Orfen» , «Ring of Core» , «Necklace of Frintezza» , «Ring of Beleth» , «Necklace of Freya» , «Blessed Necklace of Freya» . Of items, only «White Talisman of Protection» gives it - 100, while the talisman is worn.

Not used in the calculation and so do not help: «M. Def.», resistance to debuffs, stun, paralysis and mental attacks, elemental defense.

Nothing	No	45% - 69%	3.95
All Grand Boss jewelry worn	No	45% - 69%	3.98

«Arcane Chaos» on the target, but «Arcane Protection» is up	None: 30 - 30	45% - 69%	3.92
Wearing «Dark Crystal Robe»	Vulnerability 8	48.7% - 74.7%	4.16

# Protection from the steal

The steal is weakened by the same thing as any buff removal - removal resistance. The more of it, the fewer effects are lost, but the target does not become immune: the chance per effect does not go below 25%, so even under «Touch of Life» the thief takes about 2 effects out of 7 attempts on average.

Hero skills cannot be stolen, but they do give protection. Grand Boss jewelry gives no protection from removal.

The only debuff that strengthens the steal is «Arcane Chaos» : while it is on the target, the chance against each of its effects is 1.3 times higher.

A protective effect can itself be stolen if it is among the latest ones. This does not affect the rolls of the same use: resistance is calculated once, before the first attempt.

How many effects are lost on average per use (level 5 skill, thief and target level 85)

Measurement for each resistance value: how many effects are lost per use

# Cooldown

The base cooldown is 15 seconds. It is shortened by effects on the cooldown of magic skills; Casting Spd. does not affect it.

Skill cooldown

What the thief has	Cooldown
Nothing	15.0 s
«Frintezza's Necklace»	14.0 s
«Song of Renewal»	12.0 s
«Frintezza's Necklace» and «Song of Renewal»	11.2 s

# Tested on the server

The rules are verified by tests on the real server code: a character with real buffs is created, the level 5 skill is used on it from 250 to 500 times, and the number of effects lost is counted. Every skill that gives removal resistance or vulnerability was tested the same way - 42 skills, on two targets each; their measurements are in the section about protection. The measurements differ from the calculated tables above by a few hundredths.

Measured, 500 uses each (thief and target level 85 unless stated otherwise)

# Specifics of our server

The skill's logic is as close as possible to the official High Five servers (PTS). The number of attempts, the cooldown, the cast time and the number 5 in the formula are taken from their data. In the High Five update the developers announced that the steal chance was lowered and depends on the target's resistance to effect removal and on the characters' level difference. Nobody knows for certain how exactly the official server calculates this chance inside: there is no public description, and the known builds interpret the same numbers differently. So where the data leaves a choice, on our server the rule is set explicitly:

1. The chance is calculated by the same scheme as for «Cancellation» : skill level against effect level. The effect's duration is not part of the chance.
2. The level difference between the thief and the target shifts the chance by 2 points per level.
3. Without resistance the chance per effect is from 45% to 75%: the skill does not become useless against high-level effects.
4. Removal resistance lowers the chance by multiplication, but not below 25% per effect.
5. A failed attempt is used up: only the target's latest effects are checked per use.
6. Every use on a target with effects steals at least one.
7. Hero skills cannot be stolen.
