I have found much info regarding using EP on jewelry etc. but I would like to know about bettering my chances of making high loss potions. I am GM Alchemy and have a 25% Alchemy tali but even this only gives me a 45% chance of making high loss potions like DP. Does the EP help with making potions or is it strictly for the effectiveness of their use? Is there something else I should use or do to better my chances of successfully creating the potion in the first place?
