Rock Throw is a single tech performed by Ayla; Beast Toss is a double tech performed by Ayla and Robo (if playing with Duplicate Characters and Duplicate Double Techs enabled, two Aylas with Rock Throw may also use Beast Toss together).

Beast Toss, especially, is a powerful single-target physical tech. However, some enemies - perhaps due to being heavy or flying - are immune to Rock Throw/Beast Toss.

On the other hand, there exist monsters - including some bosses - that don't have that immunity built in, perhaps because in vanilla Ayla wouldn't have been available anyway.

Below you'll see tables of the enemies which cannot be harmed by Rock Throw or Beast Toss either in whole or in part. If a multipart boss has varying immunities to throws, that is noted in the table.
