How to Use Gas Arrow Effectively

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.

🏹

Projectile Scaling

Extra projectiles (GMP) and Pierce/Chain/Fork dramatically multiply your clear. Choose based on mob density.

🔥

Ignite Potential

Fire skills can inflict Ignite for sustained DoT. Invest in Ignite Duration and Fire DoT multiplier for maximum burn damage.

Duration Matters

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