Killing Dragons?

[GAME GOD FLUENT]

How do you do it as a Mage? No spoilers, but general hints in the right direction would be great. Basically, the Swamp Dragon + Fire Dragon both seemed completely immune to all my attack spells. Tried Ice attacks, Fireball and Lightning, and they didn't even damage them at all. I managed to kill the Fire Dragon by shrinking him (which was hilarious, too! :D), and the Swamp Dragon I had the help of Cipher. I'm going to hire Biff some more and his attacks seem to work, but is there a story-related reason why my magic isn't doing anything to the dragons? Again, general tips would be cool instead of outright spoilers. Thank ye!

You don't mention whether you've used the Eye of Innos on the dragon.

Else, to summon a demon as distraction, then use snapperweed or a speed potion is a pretty safe way to give you some time to kill the dragons.

[GAME GOD FLUENT]

By use the Eye of Innos, do you mean equip it and then talk to the dragon first? If so, yes, I do that. Then we stop chatting after awhile and he attacks, and none of my spells do any damage. Literally, zero damage. I tried Lightning which is my most powerful spell at 150 damage and it doesn't do anything. Cipher's crossbow was doing decent damage and Biff's sword as fine, but my attacks didn't do anything. Is this a bug or just how the dragons are resistant to magic?

Thanks for the tip for the demon summoning, though. That should help considerably in the next fight!

Edit - Also got a huge kick out of Shrink Monster working on them! That made short work of the Fire Dragon, lol.

Are you recharging your eye of innos ? You can use 1 time for each dragon

[GAME GOD FLUENT]

Yes, the Eye has been recharged. It was fully charged when I faced the Swamp Dragon and none of my magic worked against it. I recharged it and then faced the Fire Dragon, same outcome. I was able to win each battle but not with any help from me, lol. Cipher killed the first dragon pretty much and the Fire Dragon I was able to shrink and kill easily.

The fire dragon may be immune to fire damage, but you can use other spells or turn into a dragonsnapper or things like that, and then you're immune to some damage, too, such as the stone dragon's fire breath.

Maybe you've not charged your spells to increase the damage:

If you say 150 damage, that doesn't sound like it's enough for the dragon's damage resistance:

I think I Messed up with Biff, too. When I accidentally slept in a bed he disappeared and isn't back at his camp, so either he disappeared (and hopefully will reappear) or he tried walking back to camp and got killed somewhere along the way. Hope I can still progress here as I'm about to fight the Ice Dragon.

2 Demons did the trick! Quite thrilling, that one. :)
