There's a guide about this island?always collecting every 8h? thxx
When it will be "happy hour" every 4 hours.
You will want to gem monsters at about 20gems if you want a good-ish progress since at that point they don't get much less expensive over time spent.
Almost always you are done with feed/breed/hatch towards the end of each monster and only some gold tokens are left to be collected. At that point 8 hours of waiting will decrease the gemming cost by 10 gems maybe while if that time was spend on the next monster it is 100 gems because of the added objectives.
It all depends on what you want out of this island. If you want to go all the way or even go for round 2/3 you have to gem at a much higher cost.
In the past ~500 gems spread around each monster would clear you the island.
I haven't completely cleared an island since cavenfish/deadwolf one so the cost might be way off.
Around 100 gems usually gets me to previous or second previous to last but that is without missing out on any pool.
