Grass DPS
Thornwisp
Thornwisp keeps Snapshade's three-seed spread and adds Poison zones that remain for 4 seconds. The T3 gain comes from covering the lane's clash point after impact, not merely from raising the form number.
Quick Verdict
Thorn Bite leaves a poison zone behind
Thornwisp keeps Snapshade's three-seed spread and adds Poison zones that remain for 4 seconds. The T3 gain comes from covering the lane's clash point after impact, not merely from raising the form number.
Thornwisp is stage 3 of the Budboo → Snapshade → Thornwisp → Chomperwraith line and introduces the persistent zone that defines the late forms.
F2P value: Thornwisp is a useful T3 project for players who can keep enemies inside its poison zone; otherwise safer damage picks give a clearer return.

Best Modes
Good places to test
- Long, crowded lanes where enemies spend several seconds inside one area.
Be careful in
- Fast-moving waves that leave the poison zone immediately.
Compare the result with the team-building framework, Horde formation guide, and chapter formation guide.
Best Teammates
Two complementary jobs selected for this profile.
Serrabloom - Grass Tank
Serrabloom can stabilize a Grass lane so enemies stay near Thornwisp's poison zone longer.
Upgrade Priority
Priority: Formation-dependent at T3 — raise it after confirming the poison zone sits where enemies actually stop.
Mark where the frontline actually stops the pack, then place Thornwisp so its three 4-second zones overlap that clash point without changing the rest of the formation.
Pause if enemies walk out of the zone before it adds meaningful damage.
How to Get Thornwisp
- Evolves from Snapshade after completing its evolution trial.
Skills
- Thorn Bite: Shoots a seed to deal single-target damage. Sometimes shoots 3 venomous seeds to deal small AoE damage and inflict poison. Also creates a poison zone.
Strengths and Weaknesses
Strengths
- Adds persistent area coverage after the seed attack.
- Poison pressure rewards lanes that hold enemies in place.
Weaknesses

- Its result depends more on formation placement than a direct damage carry.
Common Mistakes
- Placing the poison zone behind the lane's real clash point.
- Comparing runs after changing Thornwisp and several teammates at once.
FAQ
Why is Thornwisp in B tier?
The poison zone is useful, but it needs the right lane and placement. Safer picks deliver their value with less setup.
