These elixirs doesn't need a buff at lvl 11-15 they are fine this way, you can use rock skin + lvl 9 combo for stuns at things like chaotic and go for kills instead of damage. No need to change them and if you care about stats at lvl 11-15 from those blessings get destruction or hurricane for extra hp at least.
it is enough we already have alot of buffs at mage the extra benifits of red pots arnt needed
And i agree there's enought blessings for lvl 11-15 already.
