here we go again with the mana evap talk, Ausar did a good suggestion regarding this...
Make Mana preservation stones with Mana Crystalization in a fixed recipe instead of random Synt chance.
Voila, Mana Evap problem fixed, make the 100 ones easy, make 150 ones so so, 200 ones hard, 250 very hard 300 ones ultra hard to craft.
Mage, are OP, don't make them more OP.
(And Im a bloody spellsword, this crap would simply be giving me Power, and Im the first one to say "no." so, take it as you want bois and gals)
As a full time mage with over half of my magic tab capped, magic is far from op. Windmill beats mages in most cases, and even more so when fighting groups of things your full charge int magic can't defeat in one shot. Not to mention with the current formula, int gains to damage are laughable compared to strength
* reislerenalee and dex/range, and there are practically no enchants worthy of using for mages other than a small handful.
Back on topic, mana preservation stones are also very unwieldy. Making them easier to obtain wouldn't fix the inherent problems with them, one of them being the inability to choose if you want to use it or not, or which one to use if you don't want to use your highest ones. Sure, you can drop them into a pet's inventory, but that defeats the purpose of switching mid battle. Keep them difficult to obtain as they are now, and people will continue using potions over them. Make them too easy to obtain, and then there'd be little difference between that and having no evaporation at all, as is being suggested here, other than more things clogging your inventory.
