Can't throw symbols on enemies?

[Winter Wolf]

Every other disgaea seems to have this ability but this one it always says "Target cannot be moved to that location." This needless to say is causing massive frustration as the invincible geo symbol is making life miserable.

i don't think you can throw a geo symbol onto an enemy that's currently invincible. try throwing it onto an enemy standing on a different colored geo panel.

Huh, bizarre. I had some annoying Invincible Geo Stones too, but i just threw em onto someone just fine. So yeah maybe try a different target, or stand in a different spot. Geo effects could be blocking your attempt (the "cannot pick up/throw" rule comes to mind, rare as it is).

(An alternative is using Geo Blast if you're in the Item World. That'll break any Geo Symbol at range, even if it's invincible.)

On that note, you can throw symbols onto neutral entities and item symbols to destroy the geo symbol, too. As long as it's not an player unit, they won't catch it and as a result, it will be destroyed.
(Might not work on other Geo Symbols or item spheres though due to how they often act as boxes/barrels you can walk upon. In which case thrown symbols land on top unharmed. Your best bet is throwing onto units and item symbols.)

Also geo change is good for dealing with annoying geo symbols combos, have one spare sage, (done even need to level her) and use her to change the symbols or in some cases totally remove them all. I find this is a better option.

I expect that unlocking sage would be fantastic based on prior experience with Scout in D1. But it isn't unlocked yet.

The reason it was not working is that I was confusing Tower throw and Throw. Tower throw does not operate like throw at all and probably would be better labeled something else entirely.

FYI: The Pirate class has geo change which while not 100% is a fine solution most of the time and also Geo Blast so you don't need to find a scroll. I unlocked that recently. Still not close to sage.

The nine tail fox also has those abilities (and Izuna because she is one).
