^^^^^^ that would be amazingMaybe if you hit them with a snowball they can't move for 2 seconds, that would be cool! : )
This kit is nice! It is kind of like alchemist though with the snowballs. I may just be over thinking it too much though.I see your idea but... perhaps the player has never heard of Jack Frost? So I decided to keep your idea... But do a few tweaks.
Snowman kit:
4 stacks of snowballs (for stone, 5 stacks for iron, 6 for lapiz, 7 for gold etc), that give random effects when thrown. (Like poison)
White leather armour (no enchantment for stone, protection 1 for iron, 2 for lapiz etc).
And an iron sword (no enchantment for stone, protection 1 for iron etc).
