Power-Thrust adds its percentage into the skill ratio rather than multiplying the total — five ranks, +25% at most.
Power-Thrust (also called Over Thrust) has five ranks and grants +5% ATK each, so +25% at maximum. It affects the caster and every party member on screen.
Crucially, the wiki notes that the bonus is additive for skills, not multiplicative: it is added into the skill's ratio percentage. So Cart Revolution Lv5, a 250% skill, becomes a 275% skill — not 250% × 1.25 = 312%. On a plain auto-attack (100%) it becomes 125%.
Five percent per rank across five ranks, so twenty-five percent at maximum, for the caster and party members on screen.
No, it is added into the skill's ratio. A 250% skill under a maxed Power-Thrust becomes a 275% skill rather than being multiplied by 1.25.
No. Maximum Power-Thrust affects only the caster; it is the Whitesmith's personal damage buff.
The calculator prints every step of this with your stats, gear and target, so you can check the numbers rather than take them on trust.
Builds this affects most: Blacksmith — Battle Smith (AGI).
