»Do you use Pristine Vigorous crystals? You can use 4 at a time and they restore 200 hp per crystal? I can't remember at that level, but definitely check if you can get some good ones from the npc~
The green quality level 48 crystals are 166 per tick, and they are 400g each. The vender ones I'm using at 61 per tick. I can't use the next tier up yet.
I generally stuck with these crystals until level 60, switching to Anarchic (if you can get them) on bosses in dungeons.
Either way, best of luck, Archer looks challenging to solo with, it doesn't have any dodges capable of phasing through attacks like evasive roll.
