Heres a better strategy for ragnorok: have good party (2 or 3 depending how the conditions are) and have 2 holy grails of jure, as soon as the dragons start shooting at you use the 1st grail, if you didnt kill all the dragons on the 1st try use the second one as soon as the 1st runs out.
schats:if its rosas shop after you complete the dont be proud quest(kill 20 lvl 7 wolves) or anna's quest(rescue her bear from silent hill) rosa will offer a quest where you go into rose woods to gather some honey if you do not accept that quest you will not be able to enter rosa's shop and with the armory he will give you a quest in chpt.3
