“With the Chemist perk, any chems you take last twice as long.”— In-game description
Chemist is a Fallout 3, Fallout: New Vegas and Fallout 4 perk.
Fallout 3
Effects
This perk doubles the active time for chems.
List of items
The following items will work with this perk.
Notes
- This perk synergizes well with the Chem Resistant perk, the latter providing a 50% resistance against addiction.
- Chemist affects any item which also influences the Chems Taken statistic.
- Though it specifically states that chems will last twice as long, it affects anything you can get addicted to, including alcohol.
Fallout: New Vegas
List of items
Notes
- In Hardcore mode, all positive effects (including foods, medicines, chems...) are also affected by this perk, for example: gecko steak, RadAway, stimpak, purified water, ....etc.
- Synergizes well with Chem Resistant, Fast Times, Day Tripper, Whiskey Rose and a high Survival skill.
- If you have both Chemist and Day Tripper, all consumable foods have their times increased. For example, the effects of brahmin meat normally last for 15 seconds; with these two perks it increases the duration up to 40 seconds. This is likely due to the game engine defining a chem as anything that can "wear off", which food does in the game.
- The increased duration of healing items does not show up in the list of effects for the items on the Pip-Boy.
- This perk also affects Stealth Boys, making them last 4 minutes. Combined with Stealth Girl, they can last over 8 minutes.
Fallout 4
“Any chems you take last 50% longer. Far out.”— Rank 1 description
In addition to the Chemist perk affecting the duration of chems, ranks in Chemist are needed to unlock some recipes at the chemistry station usable in settlements.
Effects
| Rank | Requirements | Description | Base ID |
|---|---|---|---|
| 1 | INT 7 | Any chems you take last 50% longer. Far out. | 000E36FF |
| 2 | INT 7, LVL 16 | Any chems you take now last twice as long. | 000E3700 |
| 3 | INT 5*, LVL 32 | Any chems you take now last an additional 150% longer. | 000E3701 |
| 4 | INT 5*, LVL 45 | Any chems you take now last an additional 200% longer. | 001D2458 |
Your Pip-Boy will show the enhanced duration of chems, though when viewing items in e.g. the crafting interface you will still see the default chem duration. *3rd and 4th ranks require 5 Intelligence as opposed to 7 due to a bug.
Notes
- In the Survival mode, Chemist rank 1 is required to manufacture many items that previously required no rank in the skill, such as a stimpak.
- When viewing the perk the "Potion Created" sound effect from Skyrim, another Bethesda RPG, can be heard.
- In Survival mode, Chemist lengthens the heal over time of many different items, including RadAway, without modifying the healing per second.
