i'd suggested to op to buy cloak since head is 95badges cost and op's shoulders are pretty good. when you'll reach enough emblems and tier-token, buy head or shoulder.
hey, wait, he already bought cloak
ps op, change your talisman to Meteorite shard (don't remember right name, sorry for spelling) from algalon-10 or to the one from ToC5ppl normal. by horrible calculations (i've made a program special for it, you can see it in my previously created themes), 128 int is nearby 50 to 70 mp5 based on your playing style. the one from ToC-5 gives you 40 to 50 mp5 + 500 mana every 45-50 seconds (~50 mp5), which mean the trinket gives you 90-100 mp5, versus 50 to 70 of the badge trinket.
p.p.s.:245+258 solace is the best trinket combo ever, since they have various id and places various spells with various id's, so they must be stacking. (124mp5+144mp5)*60/5 *7 = 37400 mana restored during 7min fight.
for the badge trinket:
305 mp5 for 15secs is 915 mana every 45-55 seconds (internal cooldown). 915 mana every 55 seconds is 83 mp5. that's not bad, but Solace 245&258, Alga-10 trinket and the one from ToC-5n is better.
