I've been checking my assumptions about what traits various things have, and what effects they have, and as far as I can tell, the "elemental" trait is actually very limited.
E.g. consider a druid with a fire elemental companion, a fire elemental familiar, who summons a fire elemental, and then shifts into elemental form as a fire elemental.
All 4 "don't need to breath" but only 2 of these 4 have immunity to "bleed, poison, sleep, paralysis".
Because those keywords are not built into the "elemental" trait, they are just things that (summoned) elementals all have, but are built into the familiar "elemental" ability.
Is this correct?
Are there any feats that allow companions with the "elemental" trait to have these immunities?
Likewise, are there any feats that allow shape shifted druids to have these immunities?
Is this something that would make sense for a future product? Would it be balanced?
