Time Invasion

The Time Invasion is a War Mode Time-themed event summoned when a Fast Clock is dropped into lava in any above ground desert, and ends once the final wave is complete. During the event, unique and highly difficult enemies spawn at high rates and attack the player. It is similar to the Frost Moon and Pumpkin moon events, though much more difficult. Unique music also plays.

The entire Time Invasion event consists of 15 waves, which progress as you reach certain kill scores (though kill scores are not displayed to the player). Each killed enemy increases the kill score by a differing amount. After a wave's required score is met, the next wave begins, and the kill score is reset to 0. Chat messages will indicate when the event advances waves, and which wave has been achieved. See the table below (Waves) for the points awarded for each enemy and the score required for each wave.

The Fast Clock that summons the Time Invasion requires materials available in Hard mode but can only be triggered in worlds that have entered War Mode. As such, it is intended to present a challenge even to players with the best possible equipment. In the final waves, multiple boss-level enemies are fought at once.

Time Invasion enemies drop powerful weapons and accessories. There are also pets and vanity items. Most drop with extreme rarity, and even players who manage to complete the event will find they need to do so several times before obtaining them all. Drop chances for Boss-dropped items increase the later the wave in which they spawn.

Tips

 * Most Time Invasion enemies are susceptible to the Ichor Debuff, which makes a Flask of Ichor or the Golden Shower spell very effective.
 * Create an Arena with several Traps to deal with the smaller enemies while you focus on The Triplets and Skeletron Mech.
 * Kill the enemies as soon as they spawn, to ensure that more enemies can spawn continuously, in order to increase the chances of surviving later waves. The arena should have predictable spawning zones and no caves where enemies can become trapped. Extra spawning layers can be created with a height of three blocks to take advantage of the anomaly of the Spiky Ball Trap that shoots up if there are two blocks below it. The Traps should all be connected together by the same wire and be activated by a Timer or by using several Yellow Pressure Plate, which ignore the player. Where the enemies spawn relative to the player depends on the game resolution. If playing in 800x600 they will spawn the closest to the player. After the event, if the spawning pads are long enough, there should be seen clusters of loot indicating where they spawn. The arena can be tested by summoning a Pirate Invasion-the invasion should be defeated in record time and a minimal number of enemies should reach the player. While using this strategy during the Time Invasion, the only serious threat will be the bosses.
