About Treasure Chests l2 pvp server

Hello there,

First of all I want to apologize for making topic in Flame section but I can't make on in PEACE General Discussions since there is no choice of start new topic. I have question regarding Treasure Chests, I wish to know the chance of them opening. On Maestro Keys it writes 100% chance of opening a chest, but I tried to open like 3 chests so far (they was only 3-4 levels above mine) and all attemps failed, chests just exploded and disappeared. I know about the level cap until 77 (6) and after 78 (5) but as I wrote before it wasn't the case.

I'm quite new in H5, played only one server of this chronicle before and there I could open all chests with 100% chance (not sure if it was modified like that), so hope for some answers. Want to know about it before grand opening.

chests on H5 doesn't unlock 100%. that is description bug more or less. Just as someone posted an old topic about chests. Remember, that you will to be to the range of chest level in order to even get a chance for reward
