Fire elemental

[Dragon5e]

After looking at air elemental I decide to check on Fire. Well so far so good hey wait this Touch attack. As far as I can tell 5e do not have touch for ac. Seem to indicate range only. After looking at multiple sites https://www.dndbeyond.com/monsters/fire-elemental. The 2 bonus need to be removed. But hey I got an answer that attacks can be dex only so air elemental get that dex slams. This is the fire ele stats.

Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns.

This was an easy fix for me. Took out the 2 bonus and take a look to see why fire ele had dex bonus but not air ele
