- Improved defenses will gain a small but noticeable purple sparkle.
- The Defense Damage Boost stat is functionally capped at 40 (~2.7x damage), with anything over this being wasted stats just for show.
- The Guardian might waste it's boosting effect on structures that gain no benefit from it, like the Magic Blockade - so it needs to be positioned precisely to affect towers which can use it's boost.

- Increased chance of being found in the Tavern Shop after completing The Ramparts on at least medium difficulty.
- Defense will be boosted in Pure Strategy mode.
