Any tips to do better with Transmuter?

Hello everyone,
I unlocked transmuter recently and was doing the "Do Cursed Oasis with Dwarves on Transmuter, Tinker and Crusader" quest and I found out I horribly suck at using Transmuters (it was by some miracle that I beat slime pit as a goblin transmuter).
I've been looking at the spirit sword (wipes all mana, adds it and 5 to your base damage every time you cross the conversion threshold) as well as the other perk that gives you +3 conversion points on glyph use as an obstacle since it seems to always happen at inopportune times (okay, I can kill this guy with three burns and a strike, so one burn, two burn... oh there went all my MP and the strike won't be strong enough to kill him... guess I'll have to drink a potion now).
I've been thinking about it a bit and I am supposing that Transmuter is really for powering up a really really strong attack against a prime target (likely the boss) since (and I haven't tried this yet) you could theoretically explore to fill up on MP, convert something, explore some more to fill up MP, convert some other things and just keep adding to your base damage for that really really powerful hit. This should kinda cool to try out, but it sounds horribly inefficient since a level 10 BURNDAYRAZ should be getting 40/6 = 6.67 damage per MP and this usage could only get perhaps 2 damage per MP use if you have 100% bonus damage.
So what are the tricks to using Transmuter well? I have video proof of doing horribly at Transmuter... but it's more of an embarrassment now and I just want to learn how to do better.
Thanks!
