Composition of an Autoscaling Magic Item

A-Z 2015 "C"I had originally planned to write about how autoscaling magic items are enchanted (“construction of an autoscaling magic item”) but it makes more sense to describe what they look like mechanically first.

Guidelines

First, consumable magic items really aren’t appropriate as autoscaling items. The whole point is that the items will grow with the wielder, and something that can be easily used up just doesn’t make sense. Items that are ‘partially consumable’ (such as a luck blade) can be viable autoscaling items because they have additional features that are permanent. “Autoscaling staves” will need to be a bit different from standard magic staves.

Second, autoscaling items by definition need to be able to become more powerful at higher levels. The Big Six are definitely candidates, other items might be appropriate.

Third, an autoscaling item will have a base effect. This base effect will likely not have any unusual requirements such as the scaling components will.

Fourth, an autoscaling item may be fully- or partially-defined. If fully-defined the items powers and effects are all known, and the wielder need only meet the requirements to gain the effect. If partially-defined then powers and effects are known only to a certain point (and the wielder need only meet the requirements to gain the effects), but the wielder has the option of extending the scaling effects.

Application

Each autoscaling item has two ‘tracks’ of effect. One is drawn from the Big Six (enhancement bonus to attack, enhancement bonus to armor, natural armor bonus, deflection bonus to armor, resistance bonus to saves, and enhancement bonus to ability scores), the other is usually a more qualitative effect.

An autoscaling item has ten ‘slots’ for effects, each associated with two character levels (first slot is associated with levels 1 and 2, second slot is associated with levels 3 and 4, and so on). Each slot will contain effects from the primary or secondary track, and will have requirements that must be met to gain access to the effect. Normally each track will have separate requirements, and it is possible to advance in only one track. Together the effects should be roughly appropriate for the level of the slot.

Example: Beobachten, the Dragon Watching

Enchanted arms and armor are the simplest to define here, since they can be expected (in the right hands) to scale from +1 to +10 effective enchantment. This aligns rather nicely with the ten slots of the autoscaling item and their associated levels.

I originally wrote about Beobachten, the Dragon Watching a few years ago, a dragon bound into sword form. For the sake of example I’ll rework it here to align with these rules.

Level Primary Secondary Requirement
1-2
3-4 spell bane
5-6 +2 bonus
7-8 flaming spell bane Appraise 7 ranks, Use Magic Device 7 ranks
9-10 +3 bonus BAB +6
11-12 flaming spell bane spellreaving Appraise 11 ranks, Use Magic Device 11 ranks
13-14 +4 bonus BAB +8
15-16 flaming burst spell bane spellreaving Appraise 15 ranks, Use Magic Device 15 ranks
17-18 +5 bonus BAB +10
19-20 seething flaming burst spell bane spellreaving Appraise 19 ranks, Use Magic Device 19 ranks

The seething weapon property is a +2 property that does +2d6 points of energy damage (in this case fire) instead of +1d6, and overlaps the effect.

The spell bane weapon property is a +1 property that acts as a normal bane weapon (additional +2 to hit and +2d6 damage) against foes that cast spells or use spell-like abilities.

The spellreaving weapon property is a +1 property forces casters and creatures using spell-like abilities to make a caster level check (DC 11 + wielder’s level) or lose a highest-level spell slot or spell-like ability daily use as if expended.

Beobachten was originally a red dragon and was bound in sword form by a wizard. He still holds a grudge (as indicated by the spell bane and spellreaving weapon properties).

The base effect is as a +2 spell bane bastard sword. This sword might be most effective in the hands of a wielder that will satisfy its lust for treasure (represented by the Appraise skill requirement) and use magic (Use Magic Device requirement) while not necessarily being a caster.

Closing Comments

Not the best example, perhaps, because Beobachten holds such a firm place in my mind with the current implementation.

It is evident to me that as written this will need either a more organic method of increasing certain effects (i.e. staging from +1 equivalent to a higher equivalent) or outright replacement as ‘more resources come available’. It may be that higher-grade effects will simply have to wait until higher level to come available, leaving empty slots in the table (which I don’t like).

Hrm. Not quite where I want to be with this.

  1. These posts are gret Keith! I’ve long had the idea of writing a Tunnels and Trolls solo where the player can collect items to make their own custom magic wepon, but I wanted the weapon to be relevant at all levels and couldn’t do it simply. You have provided the solution to this problem. Many thanks!

  2. I was going to do a solo with several quests where the player gets points for each quest depending on their success. After the quest, they could spend these points to enhance a normal weapon with more dice, more adds and special abilities. However, I wanted the weapon and the solo to be relevant to all levels, and I couldn’t work out how to do it. However, spending x points for an ability that gets stronger as you level works. (for example, you could spend x points to have your weapon do an extra 1d6 damage at level 1 which goes up by another 1d6 every level or the ability to cast a spell that either gets stronger or can be used more times as you level).
