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

  • The zone loses value when enemies keep moving.
  • 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.
