Leave dragons on "disable following" and "neutral aggressive". If not and you accidentally fall off, it will fly over you fast and to high to get back on. It will land somewhere close and die if not on neutral.
Wyverns come in seven different types. The crystal ones aren’t listed here because of word limit. The fire (short range breath attack that sets creatures on fire and does % based DMG.), the ice (also short range breath attack that applies a slow to everything it hits.), poison (spitball attack that applies a straight up amount of DMG when it hits, depending on the melee stat of the wyvern, and leaves a gas cloud that does a tick of 10 DMG no matter what. The attack is long range and travels slowly, but is easy enough to aim when it doesn’t glitch and fly off in random directions.), and the lightning (long range, easy to aim attack that does straight up tick DMG, with no linger affect). All four of the wyverns listed above spawn on ragnarok. All but the ice spawn on scorched earth. And the ice and the fire both spawn on valguero. Corrupted fire wyverns spawn in extinction, but you can’t tame (steal an egg from) them. The occasional wyvern also spawns in the gauntlet missions on genesis.
Never bring these things along with you on a journey to protect you... by the time they finally turn around to hit the thing that’s attacking you you’re already dead. But still it’s pretty cool say you own a ‘dragon’ 😅
To know how much time need to the next feeding just do the next. Look the Food number# then that number multiply x 10, then divide /3600 and the result will be the number of hours until the next time need to be fed. F.E the food number is 1850.5 1859.5x10=18595 /3600 = 5.1 hours
