Oh god, the RNG is atrocious. You could build a Mage Golem and it is stupid enough to attack four times in a row, fucking up the fight...
Or in the traditions of this server... full save pls
LMAO... the game is extremely easy as a min-maxer. Use the best pyramid equipment + dodge boots up until the last battle. In the last battle get the time skipper legs. In the beginning I always used neutral core I. When it gets available I only use neutral core II.
The Golem starts with 5 Def/MDef. Pyramid gives you massive HP + Att while reducing all Def. The issue with this is Def can only go as low as 1. So ALL Pyramid reduces your Def by 4 - that's it. You go to about 500 HP and dish out 200-500 damage per hit. My best crit was 1800 damage with 1 punch. I only ran into 1 golem that almost beat me. With all the remaining Dust get Attack Gems (the second best ones give the best bang for the buck). Time skipper allows you to attack twice per round - doubling your damage.
The mistake you make is giving a dumb-as-rocks AI a magic build which needs intelligence. Since you can't influence battles, making a idiot golem that only uses basic attacks is the only way to win (easily). Every enemy golem that used a magic built got either insta-killed on the first hit, or died on the second hit and they only do about 1/5 damage on my Golem.
P.S.: You can easily cheat on dust / HP with cheat engine (search all - all values are doubled: 200 Dust = 400)
