Hi guys, I have been playing this game for couple of month now, and have a question about the talent in the skill. Not sure which talents gives you the most effective, powerful set up for the Battle Arena but I keep getting taken out by the other players with much less BR and level. I do have all my weapons in the set of 4/4. correct Gems/ Runes, didn't mix the PATK and MATK.  other day, one of the player in my server mention that i need to adjust/activate certain talents in the skill to be more effective in the Battle Arena, but didn't specify which ones I need to activate, upgrade to get better outcome of the Battle Arena..  Attached is the screen shot of my activated talents in the Skill.  can someone show me which ones I need to activate or upgrade?  Thanks !!!

How do talent cards work? How do I get magic crystals? How do I get talent cards? Help please!

The talent "Virtual Energy" under a characters fifth and final skill is supposed to provide a reduction in energy costs. I have tested this thoroughly and even upgraded the skill to level 2 (in order to get the more easily monitored 10% reduction) and this talent does not work at all. I have included a screenshot of the skill and talent I am referring to in order to make it easier to understand which situation I am referring to.
