Fractional drain, idea for house rule Options

[darune]

Anyone has a "solution" to drain calculation when ending up with halfs ?

I was thinking: roll a die to randomly round up or down.

[Medicineman]

There are no halves !
"Round down"is official
(Manabolt 5 = Drain 2)

How about you round down (like the rules "suggest")?

... with a minimum of 1.
(Manabolt 1 = Drain 1)

Down is the way to go (IMG:style_emoticons/default/wink.gif)


ok that was more smutty then when I first thought of the reply.

From a math point of view down works best because if your going to get three drain no matter what casting at 5 or 6 you would cast at six

[darune]

Yeah, i know RAW (you round down).

This is not a big issue, i know, but it has bothered me a little that if you get 3 drain value it doesn't if you cast at Force 4 or Force 5. Apart from going into overcasting there is not really any drawback except if you need to limit netsuccesses.

So i wanted to hear if anyone has a house rule and suggested one myself.

By the by, I believe it's specifically mentioned that you can withold successes from a spellcasting test so there's no need to limit it by Force.

I too am a little unhappy about the round down since in the absence of a +ve modifier it works out the same for Force ratings 1, 2 and 3. I also prefer the notion of resisting half a DV point that isn't there to ignoring half a DV point that is there. It's also inconsistant with similar cases, such as melee damage where the DV is increased in the rounding. Still, when it's you against the players there's only so much fiat they'll let you get away with ...

From a math point of view, up works best because if you're going to get three drain no matter what when casting at 6 or 7, you would cast at seven.

As you can see, it doesn't really matter if you round up or down as far as math is concerned. Rounding will always cause one option to be better over another. The only real difference is that rounding down means the higher force spell are better than when rounding up.

But if your magic is 6, then the difference is the drain is physical, or stun (IMG:style_emoticons/default/biggrin.gif)

[Karoline]

But if you're magic is 5, then the difference in your example is physical or stun. Like I said, they're exactly the same, except that rounding down encourages a slightly higher number to be used.

Only time this isn't true is when you get to max force, because it is always an even number, and thus always a little bit more drain to max yourself out than go just slightly under max (Which is why I think it rounds down and not up).

Good observation! Ok, I like it again now.

[Draco18s]

Personally I like the rule "round in favor of the player." Which for drain means rounding down.

Surely that depends whether they have a high Awakened to mundane ratio? If the team only has the one mage and consistantly runs against strong spellcasters then they'll prefer you round up...

[Blade]

I follow the rule of "round in favor of the roller" (which AFAIK is SR's implicit rule for rounding) so that PC aren't favored over NPCs.

If I had to cover that, I'd just use the drain resistance test - if drain is rounded down, reduce an uneven number of hits by 1. That way you don't need to bother with an extra die.

For F/2 + 1 drain spell, you'd suffer:

Force 4, 3DV:
0 hits: 3
1 hit: 2
2 hits: 1
3 hits: 0
4 hits:

Force 5, 3DV

0 hits: 3
1 hit: 3
2 hits: 1
3 hits: 1
4 hits: 0

I like that. Will have to try it out. It's a bit hairy but that is maybe unavoidable.

[Smokeskin]

Had another idea: apply a -1 or -2 dice modifier to the drain resistance test if drain is rounded down.

Wow, I can't believe nobody's mentioned this before! Just switch to d20s.

I guess you are joking. But seriously, how is that going to help anything ? I don't get it.

[Karoline]

Obviously because the d20 is God's perfect creation, and using it will solve all problems, simply by virtue of using it. [/sarcasm]

I'm guessing nobody house-ruled this because nobody needs a house-rule for something that ain't broken.

[Draco18s]

I follow the rule of "round in favor of the roller" (which AFAIK is SR's implicit rule for rounding) so that PC aren't favored over NPCs.

This is what the "round in favor of the player" is, really. NPCs don't round differently because its in the player's advantage, but that the direction of rounding is chosen from a player character perspective.

Ah ok. It gets confusing when you use the term 'player' for NPCs (non-player characters).

Fair.

Im not saying the RAW is broken on this point. Just because something is not broken doesn't stop people from making house rule about and have never done so. Ill even go as far as to say that the majority of house rules out there is not ones that fixes something perceived as broken.

But i guess you are right in that nobody has tried a house rule on this..
