Exploit Weakness

Damage by level

Flat amounts and the share of Attack from SkillEffect (EffectValueList) and its level table. The game's tooltip adds your Attack to the flat part, so the damage you see in game depends on your gear. Levels above 10 are greyed: points do not buy them.

What a point buys

Our calculation from the skill tables: the flat part a level adds, divided by the points that level costs (SkillAcquireData).

Values by skill level

The numbers of the description that change with level, from SkillEffect / SkillAbnormalEffect and their level tables; column names come from the words around each number.

Raising Exploit Weakness above level 10

Points buy levels 1–10. Daevanion skill nodes and the skill effects soul binding adds to gear raise it further, up to level 40.

Daevanion nodes: +4 levels → level 14

Board	Opens at	Node cost	Cheapest path from the start	Adds
Nezekan	level 12	2 points	7 points	+1 level
Nezekan	level 12	2 points	11 points	+1 level
Vaizel	level 30	2 points	11 points	+1 level
Triniel	level 40	2 points	9 points	+1 level

From DaevanionNode: skill nodes add levels to one skill. The path cost counts every node on the cheapest way there from the board's start (our calculation, as in the planner).

Gear: soul-binding skill effects

Top, Legs, Helm, Pauldrons, Gloves, Shoes… (1,772 items): soul binding draws up to 3 skill effects, each landing with 20%; a landed effect picks Exploit Weakness 1,000 times in 10,000 and adds +1 level.

Chance one item gets it: 5.88% — 1 − (1 − 20% × 10%)³, our calculation, assuming the draws are independent.
