You will only want just enough Endurance that you midroll (70% load against your maximum load) and don't have a heavy load. Beyond that it's a little less valuable than other stats unless you are playing poorly and spam roll, over commit to attacks and permanently block etc
It's better to try and find a rhythm in battle of waiting for the right opportunity to be aggressive. If you are using a shield (good idea if you don't know a fight) using guard counters is strong, otherwise keeping moving and timing a dodge and pressing once to get the invincibility frame and position yourself for the counter while being patient and not button mashing to waste your stamina with over committed attacks (which we all anyway do even if we know its a stupid idea
)
There are a few good shields early on, vagabond starts with one and I think confessor does too, for others brass shield which drops from common soldiers wearing the triangular brass shield with a decent drop rate is great but heavy so requires more Endurance for the equip load. There are other lighter options with 100 block but less magic and elemental etc resistances. You won't have issues with the requirements as a strength build for most shields
Pretty much my last shred of magic too, super lucky!
