Energy & Tech Upgrades
Energy
Energy is your personal research currency, and suns are your steady source: every sun you own adds 1 energy per minute to your balance, shown in the Tech panel. The other source is winning — collapsing a galaxy's black hole pays out 10,000 energy in one go. Energy stays with you and is never shared inside a clan, so each player spends their own. The more suns you hold, the faster it builds up.
Tech upgrades
Spend energy in the Tech panel on five upgrades, each going up to level 100. Upgrades only help planets and swarms in the radius of a sun owned by you or a clan ally; anything outside a friendly sun's radius gets no bonus.
- Velocity (+1%/lvl): swarms launched from boosted planets travel faster.
- Construction (+0.5%/lvl): boosted planets produce probes faster.
- Defense (+1%/lvl): when a boosted planet is attacked, its garrison counts for more.
- Toughness (0.5%/lvl): when a boosted planet holds off an attack, that share of the probes it would have lost survive.
- Conversion (0.5%/lvl): super-probes cost that much less to convert when the swarm launched from near a friendly sun.
Each level costs 100 × the next level in energy, so 100 for level 1, 200 for level 2, 300 for level 3, and so on.
