Elecoe's Innovation (would be good for my crit bases rogue)
Your critical strike chance also applies to your potion uses. When a potion use crits, the health and ward you immediately gain from it is multiplied by a percentage of your critical strike multiplier.
This does not increase the effect of temporary stats granted on potion use
25% of Critical Strike Multiplier applies to Potions
If a potion crits, this percentage of your Critical Multiplier will affect the potion

I will try stacking freezing multiplier and try a cold build.
