Yes follow the pattern, 2 end then 1 spr, every time u level once add on End first, once u leveled twice and added twice on End, the 3rd time u add on spr. Keep it up till u get 25spr.
As for skillwise, i just get them all.. >_> I read about the HolyKnight/Guardian thing n heard Guardian loses access to skills unrelated to HolyKnight, I donno if it means the skill dissapears like maybe Mace mastery dissapears, bash dissapears, or what. But For now im just aiming for paladin so lol the more skills i have the more damage dealt. The faster those monster DIES!
