Hellray Harpie Demon

I would really love that. If the HP at max level would rise up to at least 2000, then that's more than enough to make me happy. He's already a big cheap powerhouse and I love him for my attacker teams. Sub attribute would also be very helpful right about now. Also, who else wants this as their pet? Come on, I'm not the only one!

Also keeps one from using it as feed for other monsters. These devils are a great, cheap, easy to skill and awaken powerhouse though. I recommend getting one of each element , wish I would've built my devil army earlier. Good for low cost dungeons, and filler when you don't have much team cost left.

you added it to your favorites. what this does is disable the option to sell it when you're selling monsters, so it ensures you won't accidentally sell it. to sell it, go to your monster box select your hellray harpie devil, and click the box that says 'remove from favorites'

Means you've put it as a favorite so you can't use it as fodder on accident

The skill up chance during x2 events is 20%, which means the chance of getting NO skill ups when fusing 3 demons is .8*.8*.8 = .512, and that translates to a 48.8% chance of getting at least one skill up.

However, the chance for each individual fodder monster is calculated independently, so it does not make a SINGLE bit of difference whether you feed 1 at a time, 3 at a time, or 5 at a time, as long as you fuse the same total number of monsters the overall chance of getting one or more skill ups is the same.

The one situation where it might be more prudent to make sure you LIMIT the number you feed at once is, say you have the demon at skill lv 25. If you feed 2 or more at once in this situation, every individual monster has a chance to give a skill up (heck, you could get 5 at once, albeit at such a low chance (.032%) that it will essentially never happen), but any extra skill ups beyond lv26 simply won't happen and will be wasted. For the demons... eh, who cares, demons are about as easy to come by as dirt and fusing 5 at once is the fastest way to get skill ups -in terms of total number of fusions you have to perform- (e.g. fusing 20 monsters 5 at a time takes only 4 fusions, fusing them 1 at a time would take 20 fusions. The efficiency /per monster/ is still unaffected), but it's relevant to consider for skill monsters that are more difficult to farm, like Hera.
