Crafting before leaving CZ220, if you’re going to be crafting, is very important, since most of the materials planetside have Level Increase properties. Unfortunately, it can get a bit grindy, heavily delaying your transition. There are also no plants on CZ220, making it impossible to level your medicine skill, and no cooking terminal, making it impossible to level cooking.
I would like to suggest that weak consumables are made available in each crafting discipline. Fabrication is fine - you can make power cores and smelt veldite. Here are my ideas.
Engineering:
Prototype Nanites - Restore 2 HP per tick for 5 ticks. Requires electronics. Amount or duration can be increased by using better materials.
Armorsmithing:
Shield Generator Gamma - Grants 2% concealment for 1 minute. Requires electronics. Amount or duration can be increased by using better materials. Also opens up the possibility of Shield Generator Beta and Alpha for later game crafting.
Weaponsmithing:
Prototype Cryogenic Ammunition - Applies +1 cold damage to ranged weapons for 1 minute. Causes 0.1 durability damage on use. Requires metal.
Prototype Tannic Coating - Applies +1 acid damage to vibro weapons for 1 minute. Causes 0.1 durability damage on use. Requires plant material to extract tannic acid.
Prototype Photonic Overclocker - Applies +1 electric damage to light weapons for 1 minute. Causes 0.1 durability damage. Requires electronics.
I haven’t been able to test medicine or cooking yet.
