It must then succeed on a second save at the same DC 1 minute later or take the same amount of damage.

Moderate Arcane Shield (Su): A steel dragon's spell resistance against 3rd- and 4th-level arcane spells is higher than normal by +10.

Poison Resistance (Ex): A steel dragon gets a +10 racial bonus on all Fortitude saving throws against poison.
