Many characters, few colors. But there are 16 million colors in HTML using RGB. I tried putting an RGB color code into the COLOR= tag, to no avail. I'll check into this more; then we would be able to use all 16 million of them, instead of just 15 named colors - even if some of us can't tell them apart that well.
BTW, if you can't see the colors well but want to know what they are, here's a trick. You can copy/paste a sample of the text in question into a word processor, for example MS Word if you happen to have it. Then you can highlight the text and then go into the FONT COLOR menu and go to CUSTOM COLORS; it will read out for you the decimal equivalent values of the hex RGB codes for the color of that highlighted, sample text. For example, using that method, it shows Janis' text color to be Red 255, Green 165, Blue 0, or RGB hex code FFA500. So if the site accepted COLOR=FFA500 as well as color words, that would produce the same result as COLOR=ORANGE, at least on this site. But you could also code COLOR=FFC520 to get a lighter shade of pretty much the same orange, or darken it down a bit with DF8500.
From 1s&0s to D&D.
About Harmless Form. First, see a handy reference:
http://www.dandwiki.com/wiki/Harmless_Form_%283.5e_Feat%29Harmless Form gives Change Shape, and help with Disguise.
Then see
http://www.dandwiki.com/wiki/SRD:Change_ShapeChange Shape specifically does not change the form of equipment, only its size. So Sheerak's weapons, etc. are visible, to answer that question.
About stacks: When mixing systems, I play that you get what you have from the system you used when the character learned or got whatever that was. For example, a D&D 2E L16 Wizard's Fireball spell that does 16D6 did not suddenly get weaker just because 3E came out with a weaker Fireball spell limited to 10D6. That Wizard clearly learned a different version of Fireball from a 3E Wizard. Unfair? Consider this: The Wizard with the puny Fireball can also learn the 2E spell. It's still out there in the Multiverse. He just happened to learn from someone who didn't know the better version. Happens all the time!
Considering all this, if the Tome says the bonus is untyped, it stacks. If the Tome says the bonus is typed, it doesn't. That's the "world" where the bonus came from.
However, before we get too far down the legal road, you should know that I don't run combat just by the numerical details, especially since the characters are from mixed systems. Huge characters with tiny shields can be hit in an unshielded tail. Unless that prehensile tail has a buckler with a smash attack... who knew? :-)
So a tiny character with two small shields (but large for him), one magically floating behind and one in front, has pretty good protection, same AC front and rear, and if the shields magically move to interpose then an attacker has to beat both of them - a pretty good example of stacked bonuses.
A huge character with the same two shields on two of four arms is not nearly as well covered, probably not much help with rear AC. Fighting one opponent, or two? Opponent has enough reach to hit the tail behind the body? Flanked? Now it's much harder to use the shields to cover everything at once; lucky to get a shield interposed at all. A pretty good example of bonuses that don't stack.
So, I appreciate everyone's efforts to define their characters clearly, but don't stress out about it... Remember it's mostly about the story.
Besides, considering what we will be going up against, we'll need all the plusses we can get, and more. A common feature of MetroMagic adventures.
