Heal and Charge with his Skill

Using Timothy's Skill triggers its effect three times, restoring 40 Health per tick (120 total) and charging the Rage Gauge by 1/10 each time (about 1/3 of the gauge overall). Because you are defenseless for roughly 5 seconds while the Skill is active, use it only when no enemies are nearby. The initial Cooldown is 40 seconds.
Becomes Easier to Use with Mastery

Unlocking the Skill Upgrade in Mastery increases the total Health restored to 240 and raises the Rage Gauge gain to approximately 80% of a full bar. If you also unlock Skill Cooldown Reduction, the Skill’s Cooldown is reduced by 10 seconds, allowing it to be reactivated in as little as 30 seconds.
Activate the Skill Before Difficult Battles

Before passing through a Judgment Gate or entering a boss battle, use the Skill to restore your Health. Because the Skill immobilizes you for roughly 5 seconds, opportunities to use it safely during boss encounters are very limited.

Timothy's Mastery Unlock Priority

Prioritize unlocking "Dodge Count +1" first. Next, acquire "Skill Upgrade," which doubles the Skill’s effectiveness, and then unlock "Skill Cooldown -3."
Priority 1: Dodge Count +1 (Req. 13,900 MP)
Unlocking "Dodge Count +1" allows you to dodge twice in succession, making it easier to evade enemy attacks. With Dodge Count set to +1 in Mastery, you can focus on acquiring Cores such as "Rage Gauge +1."
Priority 2: Skill Upgrade (Req. 12,500 MP)
We also recommend unlocking "Skill Upgrade," which doubles the Skill's effect. If you’ve already unlocked "Dodge Count +1," you can acquire it by spending 10,000 Mastery Points, subtracting 2,500 Mastery Points that overlap with the previous unlock.
Priority 3: Skill Cooldown -3 (Req. 9,000 MP)
Unlock "Skill Cooldown" after acquiring Skill Upgrade. If Skill Upgrade is already unlocked, you can advance up to "Skill Cooldown –3" by spending 4,600 Mastery Points, subtracting 4,400 overlapping points.
