What is point of lamp upgrades? For example Soft Glim-Lamp gives bonus +3 mirrors, -1 veils for 500 echoes, to overall bonus +2. For same price I can buy weapon, that gives bonus +15 iron and add special ability (torpedo, harpoons). And because otherwise it cost same to rise any ability, why wold you ever purchase lamp? Is there any hidden bonus of lamps like slower terror generation or are they simply really bad deal in game where you never have enough money?
The mirror ability is used to determine how well you illuminate your enemy, thus reducing how much time you need to spend shooting flares, seeking, etc. Mirrors can only be raised to 100 using secrets while veils can be raised to 150, so for ‘endgame’ stats you need to push them as high as possible.
The lamps are definatly not a priority upgrade, but they are still very useful later on.
Also, save up for the 1000 echo guns instead, does not take you much longer to save up for them and they’re the best.
