Buffer

The  is a Tier 5 Tank that upgrades from Sword at Level 60.

Design
The tank's weaponry is identical to the Sword and thus it looks near-identical. The only difference is a barrel-colored octagonal shell similar to that of the Kevlar that autospins.

Technical
The aforementioned gray octagon shell indicates that the Buffer, like the Kevlar before it, is immune to effects. Aside from this, it is identical to Sword.

Trivia

 * This tank was an idea by Spencer, directly coded by him during his time as Developer.
 * The Buffer, like the Kevlar, has a name relating to defense. In this context, a buffer is something that separates two other things.
