Lit all the things! Achievement 30GS
Complete all Lamplighter challenges
To gain this Achievement you will need to complete the following challenges.
Complete the Tomb in under 10 minutes
Collect the 5 Red Skulls
Kill an enemy using a Spike Wall
Don't touch the Boiling Water
Touch all 8 picture pieces
Gold challenge 85000
You can get the Spike Wall challenge done early on when you see the glowing archer crocodile lure him near the Spike wall at the start and shoot him in to it.
Boiling water happens when you light the gas so avoid falling in it but if you're unlucky and end up in it you can reload your previous checkpoint and it will count.
The last part of this tomb see's you running over tiles as they crumble and the ones you need to touch are the light colour slabs and you only need to run over them for them to count, there are 8 in total so look out for them. Again if you fail or die you can reload your previous checkpoint.
For the 85000 you will most likely need a co-op partner because avoiding getting hit on this game can be tricky and having a partner who isn't picking up gems or killing enemies makes this challenge very easy.
