Let's get stuck in that vase and placed in a coffin with these summonables!
Introduction
The Vase Weed and Coffin Zombie are tough summonable variants with heavy armor, which means them tough and very resistant to most attacks. The Vase Weed's vase and the Coffin Zombie's coffin have about 300 health, while the Weed and Browncoat inside has approximately the same amount of health as a Pumpkin Weed or Conehead Zombie. While the Vase and Coffin is still alive, they gain unique attacks that allow them to deal contact damage via their Vase or Coffin, as well as being able to shoot, and the contact damage of these summonables are increased in their Vase or Coffin. When destroyed, they only use the same attacks as the basic summonable variants. Despite their toughness to defeat, however, you can deal direct damage to them through their armor by hitting their exposed face or feet, which ignores their Vase and Coffin.
My Thoughts
Their Vases and Coffins cannot regenerate once they have been destroyed, and they become Pumpkin Weed or Conehead Zombie equivalent summonables once their armor is gone. They seem to perform fine as is, although I would suggest either giving the summonable inside a small physical health boost or give their attacks a small damage boost when the Vase or Coffin is destroyed, so they are still a decent threat even when their armor is gone. These suggested boosts when they lose their armor can still be exploited by dealing direct damage through their shields, which can be achieved by attacking their face or feet, which their armor does not cover.
Regarding their toughness, I would give them a Hard difficulty to defeat overall. They have an armor weakness, which involves shooting the summonable in the face or feet where the armor does not cover them, however this can be relatively tricky to do. Their armor makes them much tougher to defeat and they can resist attacks more easily. While they have their Vase or Coffin, they can deal improved contact damage and gain a unique shooting attack. Even when only a single Vase Weed or Coffin Zombie is present, they could pose an issue for you as their increased resistance means it will take longer to destroy them. This situation is made more difficult when needing to deal with multiple of them at once, or with other enemies present as well.
Battle for Neighborville does host the Vase Weed, but does not host the Coffin Zombie for some reason. I really do not understand why this is the case, I would rather have both of them be in the game, as direct counterparts to each other, as it would make more sense that way. I would give the Vase Weed and Coffin Zombie a 5 minute cooldown between placements, as they are quite tough to defeat and they will not be seen as often. Having to deal with lots of these summonable variants at the same time can prove to be overwhelming to your team, so this cooldown can help to prevent being swarmed by too many of these tough summonables at once.
In A Future Shooter
Due to the tough nature of these summonable variants, they should be seen quite uncommonly or rarely, and therefore should not be particularly be cheap to obtain them, especially if trying to amass them in large numbers. Due to this, I would suggest giving them a cost of about 10,000 Coins each. Additionally, there could be an unlock cost of about 50,000 Coins before Vase Weeds and Coffin Zombies, which would also provide you with a starter kit of 5 after unlocking them (which is equal to their original cost, to get you started with some after unlocking as well as unlocking for future use).
Overall
These summonables should not be easy to gain hold of in large numbers, due to these summonables being tough. Requiring an unlock before being able to use them in a future shooter before being able to use these would make them more costly to obtain towards the start of the game, but after unlock you will be able to purchase and use them freely if you would like to. While these summonables seem fine as they are, I would suggest giving small physical health and damage boosts to the Weed or Browncoat when the armor is removed to make the summonable variants slightly stronger even after their armor is gone.
