When you hit with Thorn Whip, you may decay any number of Seed Dice by one size each. For each die decayed this way, increase your Thorn Whip's Primary Die by 1.

(1/turn) Action: Roll all of your Seed Dice at their current sizes and deal that much damage to each creature within Reach 2. If 10+ damage is rolled, those creatures are Poisoned until the end of their next turn. Then, decay your Seed Dice by one size each.

Decay. When you decay a Seed Die, swap the die for the next smaller size. The die size order is d4 <- d6 <- d8 <- d10 <- d12. A Seed Die that decayed in a turn does not grow at the end of that turn.

(1/round) While Dying, you can cast Thorn Whip for free, and ignore the STR save for this cast.

Your Thorn Whip gains Vicious and "On Crit: Poison until the their next turn ends."

If you would gain a Wound, you may expend a Seed Die of size d8 or larger to ignore that Wound.
