ill just assume you are a 8vs8 looking theurgist that is there for rupt/pet-purpose and that u do not consider yourself a dps-caster. if u are windspec, ignore this post
pd3 sere3 purge1 rp1 lw1 = 4l1, absolut minimum i'd say and basic built for theurgist. from here on, youll just try to get pd/sere to 4 and get moc2 and later conc3, with 11l0 both.
+dex 2 = 4l5 (not needed imho, can use spare points while leveling up tho)
pd4 sere3 purge1 rp1 lw1 = 5l1
+ dex 2 = 5l5
pd3 sere3 purge1 rp1 lw1 moc2 = 5l6 (since conc3 is not realistic until at least 7l1 or eve 8l1 and conc2 is a waste)
+ dex 2 = 6l0
pd4 sere3 purge1 rp1 lw1 moc2 = 6l6
+ dex 2 = 7l0
pd3 sere3 purge1 rp1 lw1 conc3 = 7l1 (if u want to drop pd4 to 3 again only)
+dex 2 = 7l5
pd4 sere3 purge1 rp1 lw1 conc3 = 8l1 (since conc is uber but only on lvl3 usefull)
+ dex 2 = 8l5
pd4 sere4 purge1 rp1 lw1 conc3 = 9l1
+ dex 2 = 9l5
pd4 sere4 purge1 rp1 lw1 conc3 moc2 dex2 = 11l0
it all really depends on if u are fine with pd3/sere3. personally i'd go for 4 on each, but with pd3/sere3 u can already get conc3 at 7l1 which is pretty nice.
Do MoC affect pets? If not why to go higher then MoC1?
MoC should affect pet life duration. MoC1 reduces spells to 25%= short life duration pets=useless pets
moc1 earth pets will only last 15 seconds. wind and ice pets much less. just not worth the mana you will blow.
