Is it possible to make an Experiments .groovy bot. I cant do fight caves on my pure because i can only live a few waves.

There is already a script for this.

True

But it isn't finished and doesn't suppory food the last time I checked!

Unfortunately, no scripts seem to be able to support food as of yet.

What you could do is use the Darkfighter script and babysit it for when you need to use food.
Babysitting this bot is something I can recommend anyhow, as it cannot face all the random events yet, and since it's in BETA it could at times prove to be a bit buggy.

To set up Darkfighter all you have to do is head to experiments, start up the bot and input the ID's of the different types of experiments (or just the "Name" value "experiment" and it will work instantly.
