A damaged Shield Gas Bloon reduces damage that friendly bloons take. The tradeoff compared to Growth Gas Bloon is that it is cheaper but only affects a random bloon, and offsets health loss instead of gaining health.
If possible, avoid hitting the Shielded Gas Bloon before hitting it afterwards; doing it would make the target take less damage, because the shield took the damage instead.
Multiple Shield Gas Bloons can be used to reduce the total wholescreen damage. However, there is a chance that Shield Gas Bloon could target other Shield Gas Bloons instead.
If a Shield Gas Bloon is shielded, its health must decrease to trigger shielding another bloon.
Development
This card existed in the data of Bloons Card Storm since the Firstlook test, and was originally named "Shield Spore Bloon", though it went unused until the full release. The full release changed its effect and stats.
