Hi, i have exp boost 100% for 2 weeks. Should i spend all my gems to refill my energy to max out my kael or just max gem mine ? Because i've read first focus to spend gem is to gem mine. Sorry for my bad english.
It's a personal call. If it were me I'd invest in the gem mine. In the long run it pays for itself.
The gem mine can give you the gems you need to unlock the sparring pit, but the sparring pit can not unlock the gem mine. I would allways max the gem mine first.
And definetly don't bother about nightmare campaign. You don't have the champs to grind for xp in that stage at the start. I don't think that a fresh 6* Kael can solo nightmare campaign 12-3.

This is what I did. I'm not sure if it slowed my progress (though I suspect it may have going gems over Kael masteries), but it worked out long term for me.
I would say not spend gems on energy, patience is key. Early game you get energy for leveling up pretty fast. Do all your daily missions and just farm farm farm. Don't get sidetracked by progress missions, and definitely stay away from NM campaign as mentioned.
If you play every day you'll probably always have XP boost. I've had free XP boost for 4 months straight. My vote is also for the Gem Mine, it's the first thing I spent gems on and now I've got 7,000 gems saved up in part due to the mine.
