Practical tips you won't find on the tooltip

🌊

AoE Clearing

Invest in Area of Effect to cover more ground. Excellent for map clearing and handling packs efficiently.

💥

Crit Viable

Base 14% crit — strong crit scaling potential. Invest in crit chance + multiplier from gear and passive tree.

🎯

Crit Priority

14% base crit is exceptional. This skill is designed for crit builds — stack crit multiplier for huge damage spikes.

Duration Matters

Duration scaling extends effect uptime. Less recasting = more time dealing damage. Invest in skill duration passives.
