Eternal Star



Eternal Star is one of the bosses of 20XX. It uses the power, Shadespur, and is weak against the power, Force Nova.

Attacks with Force Nova against Eternal Star's bat minions will result in a chain reaction of Nova explosions for each bat killed.

Tactics
Consider taking on Eternal Star first because it is very, very, very cheap on higher levels. Players are essentially playing a bullet hell game, except there's also a guy who is specifically homing on them. The sooner players can get this guy out of the way, the better. Eternal Star is also here to knock out 1 of 2 Skytemple levels early in the run. Skytemple is much easier at a low level, with lesser enemy density, lasers, and moving platforms.

An alternative strategy is to fight Eternal Star last, as it is the most overwhelmingly affected by its weakness out of all the bosses. Force Nova can be used to almost completely nullify all of its attacks, and once it starts spawning bats, you can use a Force Nova to start a chain explosion strong enough to do between 1/4 and 1/2 of the boss's health.
