Also, this doesn't really help me with random encounters. Where one of the antimagic monsters can make a wave pretty much unkillable.
wot?
Did you get all the tanks and you have SoL on IA?
SoL on IA gives you 5 turns of "safety" per 50% of base SP (of which you should have more then just base).
Hit the enemies hard and fast with AoE to kill a couple so you can survive combat more traditionally.
Here is how you kill IWBTH random encounters even post level 200 without using a single potion:
Get SoL on IA (at a minimum) and if you can also get protection on IA (if you do not have 2 IA slots do not use protection for random encounters, period! too long a cast time)
Immediately on combat start cast haste, SS, shadow veil and arcane focus
in that order. (if you have extra IA slots then obviously you can replace "cast" with "IA")
Then hit enemies with X-nerf (they will hit you due to its casting speed but thanks to xnerf you will mostly likely survive that thus not wasting Spirit on SoL), then cure (if needed) and use regen 2 (trigger second enemy attack since battle started).
Then spam AoEs with a cure as needed until they are all dead. Do not use any debuffs other then that initial xnerf (you don't need to get them all, just enough so they do not one shot you even with your SS).
If you die when casting xnerf then skip casting regen2 and instead use up your cloak of fallen to cast AoEs (or 1 cure and and then AoEs)
