Solved Transformation rings

What transformation ring? Have you read this http://forum.eternalmu.com/threads/exp-boosts-seals.536854/
Are you aware of http://forum.eternalmu.com/threads/server-description.538088/
Note: Please remember that in MU (most clients) values over 65535 are visually glitched, so for any small value that you see like HP BAR or EXP GAIN it means they get visually reseted but the real value is still higher than you see, therefore while damaging a boss with let's say 1kkk, the hp bar shown at the top of the monster head will visually reset everytime you damage him with more than 65535 dmg, until he boss dies. Real value calculation will be 65535 + the value you see in your screen. This is a common visual bug in MU Online.
Example: A value of 4378 EXP obtained from high lvl monsters translates into 65535 + 4378 = 69913 REAL EXP. Watch the ingame exp bar to convince yourself.
Some custom clients running on new seasons may have this visual glitch fixed, however this is a common visual bug that exists since 2001 when MU launched.

 

@ritsard, why do you compare it with vulcanus map which has +25% extra bonus exp besides the 20% gladiator buff, being the gens war battle map? You were were not getting only 20% duel buff bonus but also the battle map advantages +25% bonus on top of that. No wonder you are confused, read the event description http://forum.eternalmu.com/threads/gens-war-event.536646/

Checked, it's totally fine. I would suggest to watch the exp bar instead of the the obtained exp if you can't tell the difference without seeing the visual bugged exp values.
I agree the visual values bugs are annoying and might confuse some of players that are new to mu but hey, this game had them for 14 years now.

1st screen, 1-2 lines no pet no ring
2nd screen, 5-6-7-8 lines panda + robot ring
3rd screen, 9-10 lines only panda
4th and 5th screen added red square

 

This was a clean test showing it works 100% fine, there is no doubt and you have the screenshot as proofs posted above. If it was something wrong with it then you would have seen it in the screenshots I have posted and it's the party testing that is innacurate not the solo one because ml uses a different game formula and exp in party is influenced by multiple factors including the fact that you have multiple other active boosts. Perform a clean test as I did and you can observe that everything works fine and there is nothing wrong.
