With the new update to Lineage II coming on 2011-11-30 to NCSoft West servers, people who levelled their characters up to level 76 will gain the ability to chose any post-awakening class (using the Stone of Destiny item) instead of being stuck with their main class default. This means that - for example - a Maestro can become not only a Tyrr Warrior, but also for example an Othell Rogue or a Sigel Knight.
As a Dwarf. a Maestro has superior (racial-based) CON, and tanks depend on high CON, so this awakening path is a tempting one. The question is however, which Maestro skills will the post-awakening skills of a Sigel Knight overwrite? Or the other way around - which unique skills - like the golem summonings or buffs - will remain?
