Good morning, Its ok to add the lesser PS.. just be sure to sandbag a few more points then you really need for the 120s.. as sometimes you get hit by what we call the round up bug.. where it still only cost like 600-800(hiryus-mares,banes,dreads) to add them all but requires you have a few points over that amount to add them like 610-810... ..then once you add the final 120s you just spend the left overs.. bare in mind that wrest,tactics,eval,ss, are 50 per 5 points or 200 for 120, magery,bush,nerco,chiv ,ect are 25 per 5 or 100 for 120 and RS,anat,parry,healing,med,focus are 5 per 5..so 20 for 120.. so on like a lesser or greater hiryu with a school of magic you would want to save 620ish... 600 for all the skills and the 20 just to play it safe in case of round up bug.. No matter what the total amount required to add 120s will be the same.. so if ya add the 105-115 first its still will only = 600 on a hiryu and 800 on a mare/bane... Just don't forget on cus there is an extra 20 from 120 healing.. so don't forget that ..I hope this helps.. if ya have anymore questions feel free to post or ask.. =^-^=
P.s. edited this abit to make it ezier to understand.. I really should stop trying to post after the meds kick in..lol
