seriously Laxus, food restores 533MP every 5 seconds (you can get food from remote store), thor's buff restores 233 mana every 7 seconds. untill lvl80 (or so) you can get a buff that restores 2k mana every 30 seconds, if you're lucky enough to get aries nebula, it restores 300 mana every 5 seconds.
as a slyr, your skills take 200-300 mana max. all you have to do is use the fucking pots/food! i've never seen you use any of those things and yet you kept crying how you're always out of mana... how is it even possible that you're the only person having problems with mana? how is it possible that my mana never goes below 50%?
you were stupid enough to max all your skills at lvl70 so it might be quite hard at first, but soon enough all those problems disappear.
you can't do nothing? what do you mean? need coins? hunt some HBs, it gets you 1.6m (3.2m since you have an alt). need some more? poseidon stamps quest gets you 500k. need even more? solo tob easy, you can get 2-3 sets of anniversary words, which gives you 300-450k. need even more? how about rocky abyss?
i have no idea what do you mean by "upgrade pet". is it a bad thing that we have to upgrade our pets here? o.0
