Which I could prob find googling but
Is more damage not that good if you dont have some / alot of increased damage ..works like that right ?

more is a flat multiplier (30% more = take your damage, multiply it by 1.3)
increased is one multiplier whose contributions are summed together (100% increased + 100% increased = 200% increased)

"more" damage is always superior to "increased", but increased is easier to get by far (you can maybe get like 15 sources of more and like >200 different sources of increased)

U want both tho If possible 🤑

Yeah dunno how familiar you are with the game but typically the "more" multipliers are almost obvious choices (say power charge on crit if you use power charges, Pain attunement if you have low life, controlled destruction for non-crit based spells, etc). They are generally very tied to the archetype of the build. But yeah you want both if possible (except say when you have minion builds that don't scale from it, things like this)

Makes sense thanks
