No more than five abilities can be used during synthesis. In the event that the number of abilities equipped exceeds this limit, five will be chosen at random.
whats the point of being able to equip 10 then? no one is gonna wanna have random abilities pop up from the 10 u equip so im assuming that people are only gonna start equipping the 5 they wanna use from now on... this makes the advantage of being 50 and equipping 10 rather pointless after 25.
