1. Upgrade Bosses
- every boss during channeling ability will have invulnerable state

Made solo runs insufferable,

DPS window is very small now for e.g. for Act 1 Boss with the correct build Sandstorm phase is the opportunity to deal as much as damage as possible.

Now the only good DPS window is during burrow phase, because you can't face tank SK when he hit you due to the stacking debuff.

Without Artifacts easy solo run goes from 50-60 minutes to 80 minutes+

At least revert this update on Solo run if multiplayer is the concern.

3. Easy mode
- now items can be sell anywhere

This should be available on all difficulties for solo.
