Engineer

You are an expert at constructing dangerous devices---and avoiding their dangerous effects! You gain the following benefits:

• Increase your Dexterity or Intelligence score by 1, to a maximum of 20.
• You gain proficiency with tinker's tools. If you are already proficient with them, you add double your proficiency bonus to checks you make with them.
• When you craft a nonmagical item using tinker's tools, it requires half the amount of materials and time to craft.
• You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this benefit, you can't be blinded, deafened, or incapacitated
