To replace the default spells, I'll start with one spell and work through my assumptions to see where it leads.

In Warrior & Wizard, the effect of the Blur spell is Blur makes it harder for others to see, hear, smell, etc. the target of the spell.  (It's Thrown, so it is applied to a target, which can include the caster.)  All attacks against the target are at a -4 penalty; any Perception Checks against the target of the spell are at -4 as well.

Here's the first of my assumptions. Checks in TFT-like games are rolling a number of d6s to be equal to or less than an attribute. Since most rolls are 3d6, I'll treat a -4 penalty to checks as a -4 penalty in The Black Hack.

The Black Hack uses Advantage and Disadvantage, usually regarded as a +4 bonus (Advantage) or -4 penalty (Disadvantage). So we'll translate the effect in terms of advantage and disadvantage. TBH uses player-facing rolls, so at least for attacks, it would be roll advantage on a DEX check to avoid damage in combat. As far as opponents Perception checks, I never really ran into that playing TBH. Still, it's just as easy to say that the player rolls with Advantage on DEX checks to avoid others perceiving physical details about you.

Okay, we have one spell effect for my Black Hack with Different Magic system underway.

    Three Quick Things:

1. Color Coded Magic - I have it on a USB Drive to make it easier to work on. As part of my new workflow, one issue I have is the inability reliably work through Google Drive or Dropbox. (I would prefer Dropbox as I have 1TB there.)

So new workflow is work from USB Drive (including portable Opera browser) for markdown, odt files, and Scribus files. At certain milestones, everything will be uploaded to Dropbox for storage.

1. The TFT Hack (for lack of a better term). I will work on this by thinking aloud on this collection. The rationale is I haven't decided how far to deviate from the D&D feeling of The Black Hack.

2. I will begin to post my working aloud sessions on my neglected website (sycarion.com). This will allow a broader audience.

I can post to WordPress with Markdown, but I will instead use an app (Open Live Writer) to post. It interrupts the workflow a bit, but until I switch platforms (not likely, but Ghost looks great) it's the easiest.

    From time to time, I've seen to blogosphere pose a question along these lines:

How would magic be different if the spells in D&D were based on something else.

For example, what if the spells were from The Fantasy Trip instead of Chainmail/OD&D?

So, using W&W, an OGL clone of The Fantasy Trip, I want to look at what that would look like for The Black Hack.

This may be a weekend project, but serves as a test of my workflow to bring crazy ideas into reality.

Once done, I have a module for my Black Hack system to add in not d&d spells.
