Goblin Alchemist Healing Spray is really good =]

[T.M.]

After testing it and calculating it's total healing amount, it's really good for a low-mana ability with no cooldown.

Level 1 only heals 105 to all units, but level 2 goes up to 200 and level 3 325.

He's probably not good as a first hero due to his average speed and the fact that it is a strength hero, but as a 2nd or maybe 3rd hero on a human army he probably owns. Imagine your low hp rifles priests sorcs etc getting healed after a nuking wave from an undead .

Low hp units = Goblin Alchemist's friends, such as archers and ghouls.

but it heals enemy units as well..(i think)
so casting it in battle might not be the best idea
but that's a nice ammount of healing indeed, you just gotta be carefull's all..

[T.M.]

It's not that hard to not heal your enemies and only heal your units, its not like he's going to run into the middle of your army just to get healed

You just gotta do sort of like the opposite of how you would use blizzard or flame strike. Just try to aim it at your units as best as you can.

it easeier to run from blizz and stirke then run into healing spray..you target so no other unit fit into the area.

heal spray is total crap in lvl 1...... at lvl 2/3 it's acceptable... which means if ur going to use this spell you better use him first......

still though i can't really think of a use for this spell... espically since it's not very likely for you to go both heal/bomb... and with higher lvl rage he is a really good fighter... why would you want to use his channal spell instead of his instant spell then?

bomb > heal by far
