Boss animations update

Hello!

This new update has many of animations for the Boss. The animations are:

• idle
• walk
• hurt
• death
• resurrection
• attack 1
• attack 2(combo)
• attack 3
• effects for all attacks

Next week I'll finish the updates for this pack for now and update Grasslands 2.0, possibly Ancient ruins too and then I'll start working on Volcano asset.

Thank you all for the support ^^
