Are there are any builds that focus on consumables?

Like featuring high lore or heavy potion use. Especially for solo.

I did one (long ago) for scrolls:
 

It's bascially a Rogue who combines Deathblows with spell damage (+100%). Direct damage spells profit from Deathblows (bot not from Sneak Attack). Rogues can use spellbinding, spellholding and spellstriking gear to get spells - and of course scrolls. 

It's not a solo build though.

For solo:
A Fighter could use the same concept - not for the damage boost with Deathblows ofc., but scrolls in combination with his high base accuray and Disciplined Barrage (+10 Acc). Fighters are usually quite limited when it comes to AoE, especially disables and CC, which makes them meh at soloing - at least on PotD. With the right spells from spellbinding and scrolls and that high accuracy this is mendable. At the same time they have great base stats (acc, health, endurance, defenses) - which is nice for solo. High INT and PER are important I think. High INT and PER are also very nice with Clear Out. It's per rest - but your other spells are per rest (or consumables) are per rest, too, so Clear Out is not really adding restriction - it also works like a spell (no weapon involved actually) and it's very strong with high INT (big AoE and long prone).  

There is no need for a special build for potions imo. They don't change their workings no matter which class or build you use. Potion drinking animation is buggy (or was, maybe it got fixed with the current beta).
