"This is one of many builds that I made while playing a modded 1.3 world on-and-off, with mods such as Calamity, Thorium, and Shadows of Abaddon among others.

I typically don't build dedicated arenas, preferring instead to adapt to whatever surroundings I find. However, the jungle dragon's unique approach to battling necessitated the construction of one. I found it fitting to start with mudstone, iridescent bricks, and perennial bricks (Calamity). Adding purple, red, and orange gemspark blocks gave the impression of hard-light beams, which are functional with a switch on a raised platform in the arena! (Not pictured: Raised platform, halfway to space.)

Lastly, once I found the materials required, I added the resulting silva crystal set to the build. In addition to filling the holes that I left in the arena specifically for the silva blocks, I built a small room with stained glass windows, plus the surrounding 'hallways', around the arena.

(As a fun fact, this build doesn't have a Worldforge link (a teleporter to the hub) for two reasons: its proximity to two other builds with links, and the ease of access to here at this point. The arena ended up being perfect for a certain other superhardmode boss as well.)"
