Explosive Concoction Working with disabled flasks

So it seems that explosive concoction still gets bonuses from flasks even with the toad's price from the nameless ascendancy. As long as you had your flasks equiped before you take the node the skill will keep consuming charges from those flasks.
I've tested this with a level 1 explosive concoction against some bosses and the difference is clear. once you unequip the flasks you can't re-equip them and the damage is noticeable lower.
This is based on an ignite based elementalist version of the build.
