'''Boost to Ql when imping:''' Imping with 100 armorsmith imbue tools seems to increase the amount of ql an item gains upon a successful imp versus a un-imbued tool. I haven't collected actual data on this but it seems to be around double or triple the ql increase compared to a unimbued tool.
'''Storelot on CA-Help mentioned (11/17/22):'''
"for creation it massively increases average ql but not max ql, imping it increases how far over your skill you can imp". They also said that "at 100 power it doubles the normal ql cap, like at 90 skill you can imp to 92.3ql, with 100 imbue you can imp to 94.6ql for example".
