Tap Adventure had a great loot system built into it's progression. https://play.google.com/store/apps/details?id=com.kongregate.mobile.tapadventure.google
Idle Loot Quest is also great...it's literally built ALL around loot in the game: https://play.google.com/store/apps/details?id=com.topcog.idlelootquest
Tap Adventure - nice and smooth graphics. Also registers several taps, so you can tap with 1-2-3-4-5 fingers at once.
Just came out of beta and is now live. It's part 2 from the original Tap Adventurers and improves on it quite a bit (imo). I've been having a blast so far.
If you've played the old one a bit you can gain an artifact called the Chronosphere once you reach stage 100. If you haven't played the old one, you will be able to buy the sphere after (probably) about a week of playing using currency earned in-game.
PS I misspelled the games name slightly in my title so don't hate me too much.
It is also out on Mobile but currently (I don't think) there is no way to share progress between the two. No clue if it's coming in the future or not as I've never touched the mobile version. Android
Here are two new player guides if you need them:
One tip is if you're going to click (or use an autoclicker, the dev said he was fine with people using them.. game is capped to 20 CPS), go turn the Battle menu and turn on Golden Touch. It grants 4x gold from magic (click) kills.. lasts an hour. But it has a 6? or 8 hour cooldown (reset on prestige/time loop) so only use it if you'll be clicking for a bit.
Tap Adventure: Time Travel ? Came out in 2016 but has been since 2015 on kongregate.
Same, but on the Android version: https://play.google.com/store/apps/details?id=com.kongregate.mobile.tapadventure.google
