Make digging at the battlefield faster

[Fatt_Shade]

Nice idea, rarely i found some1 messing with rage skills
But could use a bit of polishing. I`ll try it later to see what to change for my game, but here`s couple thoughts :
1) make it spend rage as for digging 3 chests =15-20 rage on max lvl,
2) and use pet turn (spending 3 or more turns with dragon was tedious, but not spending even 1 turn for him digging all chest in arena is a bit much).
So how about removing evil chests ( i have never dig 1 of those and i finished this game 4 times with over 900 chests in every game), and treasure searcher using 1 turn to dig all chests and sending 5 rage for 1/10 for 2/15 for 3/20 for 4 chest ( I added 1 more chest in my red sands mod and pet dragon up to 65 lvl).His digging skill would look like this :

  digger {
    hinthead=pet_digger_name
    class=scripted
    script_calccells=calccells_digger
    script_attack=pet_digger
    attack_cursor=magicstick
    place=2
    level=2
    default=level1
    upgrade {
      level1=level:0/green:1,rage:5,rest:1,exp:5,level:1
      level2=level:1/green:2,rage:+5,exp:+5,level:2
      level3=level:2/green:3,rage:+5,exp:+5,level:3
      level4=level:3/green:4,rage:+5,exp:+5,level:4
      rage1=rs:0,level:>0,rage:>5/rage:-2,rs:1,exp:+7
      rage2=rs:1,LV:>10,rage:>10/rage:-2,rs:2,exp:+8     
    }
  }

Thoughts ?
