Antidote is a defensive buff which gives the caster +2% spell armour per rank against poison damage. If you enhance the spell, the duration is doubled and you get an additional +1% internal poison immunity per rank over 20. Recasting the spell will renew the duration but leave the bonuses, allowing you to cast an enhanced version once and then maintain the immunity with unenhanced spells.
