Now recently my team went up against another in Team Wars. The Rules were Underworld, Metal and Metal. Alot of the enemy team members were using Hercule as their defense monster on one of the metal rules. While battle one of the members with a Hercule in their defense, i stumbled across something interesting.
I didn't remember seeing it but I'm assuming that he used Field Day first which gives him 25% damage mirror. Then the Hercule used Just What i needed, as i sort of expected, it reflected back and it said '140 Stamina'. That was that. Things got weird the third time he used the combo in the battle. It recharge his life to full as i hadn't damaged him that much but after that, i can't remember the exact number but I saw that it said a number between '3300 Stamina' and '3395 Stamina.'
That in itself is weird, the fourth time he did the combo, it healed him to full health and it recharged '0 Stamina'. I was able to get a screenshot of the 0 stamina one but i didn't react fast enough to the 3300 one.
As for the name of the topic, the bug would be the Damage Mirror reflecting his self skill and producing weird numbers and the Exploit would be, because the Damage Mirror reflects his self skill, Hercule gets 2 extra moves instead of 1.
