histortion

Anathema is on a patch that has them. I've caught plenty of oily blackmouth on Darrowshire (patch 1.5). In 20 minutes of fishing I caught 7 blackmouth and 3 nightfin.

Regrowth is only bad if you're overhealing. The mana per point heal is pretty equivalent to HT/rejuv (at least when I compared the values a couple levels back). Additionally, having two regen effects on the tank gives you more time to regen mana before breaking the 5 second rule again. Your tank shouldn't be lower level than the mobs. They could have excellent equipment, but damage mitigation is crippled vs higher level mobs.

It's a secret. I'll tell you I've caught them in high level areas and nightfin are just as un/common.

you can catch them without pools

I'm levelling. Hopefully people stick it out so we can group when I'm at max.
