'Fifteen minutes is quite a lot but it will get less as I level the skill up, right?'
'That's not a problem, I've been holding my ground without this skill and I will continue to do that. Once I use it and it starts cooling down, I'll just try hard to deal with those dangerous high balls until the cooldown is over.'
'If I knew this skill would evolve into this, I would have leveled it up a long time ago.'
'Yeah, I forgot to put those into consideration.' He said before putting his hand on the back of his head. 'So what other skill can be evolved into something better?'
'Yeah.'
'Why not.'
