So, I noticed the following by clicking and haven't been able to find anything here on the official forums. I asked a few friends and they knew nothing but, as I guess most don't know, out of the eastern fragments both Sentimental and Cursed Fragments are consumables.
From my testing, it seems Divine-Pride has it reversed and is missing some info:
- Sentimental Fragments warps you to Bio 5 dungeon (Tomb of the Fallen)
- Cursed Fragments does a variety of things: curses/bleeds/stuns/etc you for 5 seconds, shows dialogues with no discernible effect, casts Assumptio Lvl. 5 on player......but it can also BUFF YOU FOR 10 MINUTES WITH +50 ATK/MATK!
When getting the above bonus the message ""I will never forgive you" is shown. It uses the same icon as Donut/Poring Pretzel/Takoyaki (so I presume it overtakes the Donut's bonuses) but instead of a +10 ATK its a +50 ATK bonus! Expensive when contrasting the market price of both but if you got the zeny, more powah to you!
