|~ BMC Special Rules before attacking a Phase Crystal tile|
The Phase Crystal is a Special tile in Bloons Monkey City. Players must defend against 26 rounds of double-speed Bloons. The crystals in the middle has an ability identical to the Technological Terror's Bloon Annihilation (even the glitch that prevents it from popping camos), except with a cooldown of only 15 seconds. This tile is required for the Crystal Fusion Array special building to research the Ray of Doom for the Dartling Gun. Completing this tile earns 1500 XP, at least 3500 and 50.
The Phase Crystal ability, which has a fairly short cooldown in comparison to most other ability cooldowns, will completely annihilate all bloons in a short radius of the Phase Crystal (basically a couple tower widths down each path, towards the edges of the screen) up to and including BFBs (which is the highest level bloon during the battle). Judicious use of the Phase Crystal ability is perhaps the single greatest factor for ensuring success. It is capable of taking out most mid-level leads, and many of the later MOAB classes, including (importantly) all of the BFBs. There are at least two deployed bloon schemes, one with MOABs earlier and more often, the other more focused on regular bloon rushes. If you get your first MOAB at round 16 you should gear future towers towards MOAB disabling/damaging, otherwise for dealing with bloon rushes. Again, as most MOABs can be dealt with with the Phase Crystal ability, a tendency towards preparing for rushes is probably a safer bet, all things being equal.
Bloons will come out of only 4 of the 8 entrances/exits:
- Top Left Top
- Top Left Left
- Top Right Right
- Bottom Right Bottom
- Consequently (as utilized in the next strategy) initial tower placement should generally ignore the bottom left corner.
Strategy by AnonymousEdit
A very effective starting strategy: 3 ninjas - 1 in each corner except bottom left. Get them all up to 1/1 then 3/1. Phase Crystal any leads or big rushes (First big rush comes at level 8 and first leads at level 9). Pineapple if needed. If you lose due to leads, retry and get a 2/1 glue next to each entrance, set to Close. If ceramics kill you, be ready to phase them or get distraction, possibly Bloonjitsu. Once you have 3 Bloonjitsus, spam them till you win. Phase any MOABs or BFBs.
Strategy by Qwertyxp2000 the secondEdit
I based my strategy upon the strategy by anonymous. I started with $3450 starting cash. I put 3 ninjas one in each corner, excepting the bottom-left. You may use any free Dart Monkeys given, where you can put them anywhere around the Phase Crystal. Upgraded all to 1/1, except the top-left one, which has Sharp Shurikens (if you have a smaller budget, upgrade all to 0/1). I upgraded the ninjas to Sharp Shurikens and then Distraction. Added a 2/1 Glue Gunner at the right and left of the Phase Crystal to pop nasty leads. Random Guy's Tip: (After that, just continue upgrading your ninjas to bloonjitsus and if you have about 3 in the top left and 2 in the other corners, make sure you get your glue'ers 3/2 after that. (This is because some of the other bloons will get through because the leads block the ninjas shurikens from popping them.) )
- The description states that the Phase Crystal powers the Robo Monkey's power suit. However, it isn't required for the Biomech Enhancements Building.
- You can place the Fiery Pit Building on a Phase Crystal and also a fire master can be seen meditating on the tile.
- Despite the Phase Crystals having the Bloon Annihilation ability, this tile is needed for the Crystal Fusion Array (Ray of Doom) and not the Antimatter Weapons Facility (Technological Terror), which has the same ability.
