Sacrifice works just fine on level 5s - but keep in mind a lot of them (like most dragons) are immune to magic. You also can't use it in any way on summons, like the plants a Royal Thorn summons (but it works on the Royal Thorns themselves).

As Marc said, it definitely works on level 5s. I just used it to create a green dragon (thank you, blade of pain... +10% sacrifice power hehehe).

SOME dragons... There are... what? 2 units in this game immune to magic?

Also, on that note, has anyone else noticed that Geyser now hits Black Dragons?

Book of Evil, Phoenix, Black and Ice Dragons, Chaos Dragon

are you sure? cause when I tried to kill my paladins to create new royal thorns I got the same question mark I got on ice dragons? are you sure plants aren't immune to this? like they are immune to many forms of healing?

Maybe because your power is too weak to create a new Royal Thorn.

I absolutely noticed, no fair! :) But seriously, I just think it's another bug. It's "immunity to magic" not "immunity to magic except Geyser" right?

Maybe it's immune to spells that specifically target it, but not collateral AoE damage. Has anyone tried other AoE spells on them?

(I'm not saying that's how it 'should' work, just that it might have been implemented this way in WoTN. But if it's only Geyser then yeah, probably a bug)

well... remember the armageddon+black dragon combo? yeah... immune to all meant immune to all, eh?

Not sure if sarcasm or not. Blacks have never been immune to armageddon.

@Zechnophobe: I was only counting non-summons, although it is weird that, as someone who uses lots of summons, I'd forgotten those had magic immunity, too. Still.

Actually, the bug with Geyser and Black Dragons... I believe it occured sometime in Crossworlds latter patches.

If you go SOLO Black Dragon stack, you can't "target" the black dragon with geyser, therefore the black dragon cannot be hit with geyser. IF he goes with an army, he CAN be hit (which I think is stupid).

I just really remember running with a black dragon with my armies and never getting with with geyser. Maybe it was all a dream...
