Comboing powers could work but the closest we have already is powers like sneak attack, toxic shock, or Will-o-wisp where they gain an effect basis on if you already did some set up. There is also combos likes grease and fireball but that is more set up then combo too. These are all set up and really its hard to get out of that kind of system. Sneak attack is a funny power that wants the user to be a charmer to abuse fully as you want the extra turns of obscurement to gain about plus 300 attack power and about plus 90 accuracy. This combo of sorts in only in one move and is unique for doing it. Toxic stock is just Venoshock really when you think about it. Will-o-wisp is similar but spread when the debuff is there.
Not sure if multi power types of combos would even see use outside of things like grease where it is also a stun. people don't seem like they have the appetite for those power types
(This is also an resume and betterment of my previous post's ideia explanation)
Probably powers that require an previous buildup like
Firewyrms's mechanic so to enhance it's effect could be utilzed to instead of having it simply amplify it's damage if used successively without any interruption it would get some sort of visible stack buff to the user wich would display the current number of the buildup.
Wich if used with any other none-included
Finisher Powers* the total acummulated stack would be lost, yet when used with an included
Finsiher Powers* it would consume the total necessary numbers of stack and do an extra effect if the previous condition were met.
Than the above could continue in creating an different type of stack buff for use with subsequent levels of
Powers.
*Finisher
Powers are normal but with an added mechanic wich is the finsher effect that would thrigger if the conditions were to be met by having enough stacks of the required stack buffs (
Basic Stack Buff,
Advanced Stack Buff and
Expert Stack Buff), wich could be utilized by using only one of them or in any combination for requirments of effects to trigger (some can also use and/or combinations wich has it do a stronger or weaker total effect depending wich stack buffs were available on the use of the
Power, ex.: it would require 2
Advanced Stack Buff and 1
Expert Stack Buff or
Basic Stack Buff [if there was only the
Basic Stack Buff it would perform the lesser strenght version of the
Power's
Finsher effect]).
Ex. 1º: 'Chain Strike'
Recharge Finisher Power requires an 3
Basic Stack Buff's for it to additionally trigger it's stack effect, else it would just do the normal
Power's ability without the stack effect (or it could be unconditionally needed for the power to be used, thus the power being able to not have an CD).
Ex. 2º: 'Dirte Deed'
Encounter Finsher Power requires 2
Basic Stack Buff's and 2
Advanced Stack Buff's for it to additionally trigger it's stack effect, else it would just do the normal
Power's ability without the stack effect (or it could be unconditionally needed for the power to be used, thus the power being able to not have an CD).
At-Will Powers give
Basic Stack Buff for
Recharge,
Encounter and
Ultimate Finsiher
Powers;
Recharge Powers give
Advanced Stack Buff for
Recharge, Encounter and
Ultimate Finsisher
Powers;
Encounter Powers give
Expert Stack Buff for
Recharge and
Ultimate Finsisher
Powers.
P.S. - This could also be utilized as an
Class specific mechanic, in wich you would gain the possibility of gaining stacks only if you were to be the refered
Class (in this case it would be the
Thief).
Else the normal version of the those
Class Powers would still be available for other
Classes to use, but as they are not proficient in the way of the said
Class they cannot bring out the full potential of said
Class Powers.
