Since last update, you gave that kit another OP features, like buffed pots:
• Speed pot now gives it 30 secs of speed II + 3 mins of speed I effect.
So you should take away those 3 mins of speed I and leave 2 pots for 45 secs of speed II instead.
• Poison pot now gives it 6 secs of poison II and 45 secs of poison I. Almost 1 min of the most awful debuff, which makes this kit almost undefeatable.
So you should completely remove poison pot from that kit.
• Wizard deals 10 damage per hit (7 dmg sword + 3 dmg pot) and that's too strong.
You should decrease the damage for 1 (to 9 dmg) by decreasing sword damage for 1 (to 6).
Instead, you can give Wizard 1 iron armor part like helmet, leggings, or boots with feather falling I or II + protection II or III enchant.
• So for now, it makes other kits like Beast, Warrior, Berserker, etc. literally unplayable against Wizard.
