MC14 Fiend Folio said:Combat: When a fyrefly is doused with water or hit with a cold-based spell, it falls into dormancy. It appears dead, but will awaken in 24 hours and begin its feeding process again.
MC14 Fiend Folio said:When a fyrefly comes in contact with a flammable object, there is a chance it will burst into flame. To determine this chance, first determine the flammability of the object in question. On an average fighter, for example, perhaps only 10% of his/her attire would be flammable, while on a wizard almost 90% would be. On any hit, roll percentile dice to see if the fyrefly hit a flammable object. Any flammable object hit by a fyrefly, adult or larval, must save vs. normal fire or be set ablaze. Persons in burning clothing suffer 1-6 hit points of damage per round until the fire is extinguished. Hits that do not strike burnable objects are assumed to hit flesh, causing 1 hit point damage.
MC14 Fiend Folio said:The fyrefly will only attack living creatures while it is in its larval stage, immediately after it has reproduced (see below.) At this time, it becomes frenzied, and will seek to set fire to any living creature. When the fyrefly is in this agitated state, it becomes extremely aggressive, and attacks as a 5 HD monster (THACO 15). Because of its extreme quickness, it becomes much more difficult to hit, with an effective Armor Class of 5. (If, for some reason, a larval fyrefly is resting, its Armor Class falls to 9.) During its aggressive phase, it flies at anything that moves, believing itself to be invincible.
MC14 Fiend Folio said:When in its larval state, the fyrefly is immune to fire and fire-based attacks, but cold-based attacks will immediately cause the creature to fall dormant. Water splashed on a larval fyrefly will also cause dormancy if the insect fails a saving throw vs. paralysis.
MC14 Fiend Folio said:Larval fyreflies will swarm, and area of effect spells will have a reasonable chance to take out most of the creatures, but 10% of the creatures will always survive such an attack. Remember that larval fyreflies; usually swarm around a creature, and an area of effect spell will undoubtedly affect that creature, also.
MC14 Fiend Folio said:Habitat/Society: The adult fyrefly is a solitary insect, which lives in forested areas. Fyreflies spend most of their time gathering food and sleeping, waiting until the day they are to reproduce. Fyreflies voluntarily avoid others of their species, moving off into their own separate feeding areas. They sleep during the day, and feed constantly at night, pausing only to move to another leaf.
MC14 Fiend Folio said:A swarm of larval fyreflies are born from one fyrefly which has fed constantly for two months. The fyrefly will seek out a fire to fly into in order to reproduce. The 'fly is not killed by the fire, but rather reverts to its larval state to reproduce. It metamorphoses into a small, insect-shaped mote of extremely hot fire. This may be noticed by a much brighter area inside the fire into which the fyrefly has flown. At this time, it begins a process of division, which, if left unchecked, will produce dozens of tiny balls of flame. If the fire is quenched while the parent fyrefly waits to split, the fly will be unable to reproduce, and will bum out in 10 minutes. If the fyrefly is undisturbed, it will produce two larval fyreflies after 10 minutes in the fire. The original 'fly dies, but its two offspring remain in the fire. For each succeeding round, each will generate two offspring, after which they leave the flame. So, two rounds after the first split, 2 fyrefly larva leave the main fire, 4 the following round, then 8, then 16, then 32, and finally 64. The final 64 fyreflies are incapable of producing any more offspring at this time. After a larval fyrefly leaves the fire, it burns until it is killed or sent into dormancy, or until 10 rounds have elapsed, when it falls dormant on its own and begins its transition to adulthood. This transition takes 9 days.
MC14 Fiend Folio said:Ecology: Fyreflies are the creation of the mad wizard Grebdews, who accidentally allowed his "pets" to escape into the world.
MC14 Fiend Folio said:Fyreflies would pose no problem to mankind were it not for their peculiar breeding habits. They are prized for use in many fire-based potions.
Shade said:Merging a modified froghemoth ability and the comatose effects of the eyebite spell..
Partial Immunity to Cold (Ex): The fyrefly is partially immune to cold damage. Each time it would normally take damage from a cold attack, it takes no damage but is instead falls into a catatonic coma for 24 hours. During this time, it cannot be awakened by any means. This is not a sleep effect.
Shade said:Modified rage with an AC bonus?
Shade said:Swarm subtype?
Shade said:Modify the modified split ability we gave the dhour?
Shade said:Supports magical beast, does it not?
Shade said:Flavor text only, or an actual game effect? Maybe potions that deal fire damage deal an additional point, while potions that resist fire add 1 to the resistance?
BOZ said:not sure about the taking no damage, but then again let's face it; if it has 1 hp, and it takes any damage from anything at all it dies. So, maybe the no damage is just fine.![]()
BOZ said:actually, I was thinking Dex 18+ with Weapon Finesse would take care of that. I don't know about dealing with the larval stage. If we do use the rage ability, it will have to be heavily modified.![]()
BOZ said:only if we do the larva as a separate stat block.![]()
BOZ said:naah, mostly flavor text.
