Also, can you (or someone you know with access to another server or NA Test) do a confirmation check on the Bard Talent Bonus too? It gets changed in one of the updates as well.
Do you mean the base bonus? The talentdesc.xml has 10 STR and 15 SP as base stat bonus.
No, the talent bonus is the stats increased by having a high level in a certain talent (even if that's not your active talent.)
Oh, I understand what you mean now.
It is the same as the description Soluna posted in Mabidata, finalized update section.
At lv 16 (grandmaster), you have 15 STR, 15 HP, music duration +50% and music buff +5. At lv 15, you have 15 STR, 15 HP, music duration +30%... where you are getting 1 HP, 1 STR and 2% music duration per level.
