This massive shield is used frequently in organized armies for its effectiveness at protecting soldiers and aiding in the formation of lines.
While you are holding a tower shield:
- +2 AC
- You have disadvantage on attack rolls.
- You have half cover.
- You can spend an amount of movement equal to half your speed to have three-quarters cover until the start of your next turn. If you do this, then when you are an obstacle to a target [PHB. p. 196] you grant three-quarters cover instead of half cover.
