Är det möjligt att uppgradera mekanisten för UA Artificer (sid 4 i det länkade dokumentet )? Beskrivningen av tjänaren nämner inte denna möjlighet i dess beskrivning. För enkelhets skull presenteras den relevanta textpassagen här:
At 6th level, your research and mastery of your craft allow you to
produce a mechanical servant. The servant is a construct that obeys
your commands without hesitation and functions in combat to protect
you. Though magic fuels its creation, the servant is not magical
itself. You are assumed to have been working on the servant for quite
some time, finally finishing it during a short or long rest after you
reach 6th level.
Select a Large beast with a challenge rating of 2 or less. The servant
uses that beast's game statistics, but it can look however you like,
as long as its form is appropriate for its statistics. It has the
following modifications:
- It is a construct instead of a beast.
- It can't be charmed.
- It is immune to poison damage and the poisoned condition.
- It gains darkvision with a range of 60 feet if it doesn't have it already.
- It understands the languages you can speak when you create it, butit can't speak.
- If you are the target of a melee attack and the servant is within 5 feet of the attacker, you can use your reaction to command the
servant to respond, using its reaction to make a melee attack against
the attacker.
The servant obeys your orders to the best of its ability. In combat, it rolls its own initiative and acts on its own.
If the servant is killed, it can be returned to life via normal means,
such as with the revivify spell. In addition, over the course of a
long rest, you can repair a slain servant if you have access to its
body. It returns to life with 1 hit point at the end of the rest. If
the servant is beyond recovery, you can build a new one with one week
of work (eight hours each day) and 1,000 gp of raw materials.
Som du kan se det står ingenstans att du kan eller inte kan uppgradera den för att förbättra den statistik du valde först. Jag tycker personligen att det är upp till GM: s digression att tillåta det eller inte.
