I see what you did there and i love it
Assassin is not the problem the problem is how it was done on zircon files,
I kinda miss alot of the old things,
Store is a NPC and can only be viewed when you in town.
Same as Market was a NPC.
if you want to to have the classic effect you will need to redo alot of skills, getting power spells at the wrong level, Defiance/Renounce, depending on the version of files you have iv seen them spells level 30 maybe even level 20 or so, if i remeber right thats 44 or 40ish level spell.
also you will need to remove the sin spell that gives them life steel that makes the class to powerful, you will need to add the LS set that you can get from apes, this was removed from Zircon for some reason. only way to control Sin is put them back to single target, they have some AOE spells for lower level mobs once they higher level(NOT MASSACRE)
Id like to see Sin with Karma and Rake spells again.
Bit controversial here but i miss the old days where drops where shared, if something was dropped you would dice for it or decide who gets it. that feels like real mir to me.
and the repair timer good times
