Isn't the artist for lv 1-2 and 3-5 different ? Sadly I think the 1-2 art are REALLY great, and the 3-5 are usually just meh...
Anyone know the name of the first artist ? I Wasn't really able to find it.
If I'm not wrong, your "all damage" bonus affect both your your tap damage and all damage. So when you have 0.4 dps to tap damage, it's [dps (base unit dps * all damage)] * 0.4 * [all damage]
So all damage kinda works exponentially on tap damage.
I can't recommend buying artefact with gems. You can have duplicates (that doesn't seem to give anything. Like, a pure waste of gems).
If you don't have much artifacts you could try to buy one or two, but it doesn't really feel worth.
It doesn't really feel useful on lv up moe girls too : when you reach the last stage (2k for now) you loop on a stage with a boss giving hearts. And since you've got a new hero at stage ~ 1800 it's a point when you mostly one shot everything. It takes about ~5 min to have a full heart (with the mirror that remove 5 small mobs each stage).
