Dragomon skill (yellow) Advanced Strength is quite confusing... It appears on Otter the Bodyguard, so it implies that it's an offensive skill, however, the first lvl says that it adds 30% defense. If you go to lvl the skill, it changes to 36% attack power, and then stays that way for any additional upgrades. Is this skill indeed giving attack power at lvl 1? or defense like it says until you spend 400 books to make it lvl2 attack power. Also, The lvl1 Defense text led me to believe it was for a tank pretty early on, and I ended up putting advanced strength on my Mr. Scales. Is it worth putting a ticket in to try to get the skill and 400 books back spent making it lvl2? or do is that a lost cause?
