Basically, a Giant snake, that spits molten blood at you.
I would say that it would have a rare chance of it spawning it on its own.
BUT, The scent of blood on the ground would raise the spawn rate of the adders depending on how much blood is on the ground in the loaded area.
instead of having normal snake fangs they would probably have rows of razor sharp teeth that would probably cut through flesh easily and inflict bleeding alot whenever they bite you.
as for their secondary attack, i think it could be simple, just make it to where it acts sorta like a boomer or something where it covers you in blood. if you know one of the property’s of blood is that it likes to heat up a lot when it is unregulated. which would inflict a status defect that you are heating up and by quite a bit all over the body.
Hp 100-400 range, for have you seen how large the spiders have grown
Bite attack 20 - 50 slashing damage, somewhere in that range
Spit blood- range 3-6 tiles, leaves behind more pools of blood.
If there is no blood in the area i would think that you just came across one or it recently rained before it aggro’ed to you and i don’t think it would be too aggressive and would move at a standard 100 speed
If there is blood and depending on how much it works itself into a frenzy attacking the player/eating corpses as it comes across them… gains 1 speed per puddle of blood it is near (5 tile radius) and 5 per pool. and will be able to recharge spit blood faster
and increase the rate at which they attack and spit blood… to a certain extent to where it doesn’t get too ridiculous… i could see some unlucky person that Rng Hates and getting mauled by 5 of them
Regenerates 10 hp per 5 turns while fighting… blood around the area/ eating corpses could increase the effect.
Movement- as of somewhere above gains speed while near blood, but i think it may be appropriate to lower its base speed to 80-60 and increase speed gain from blood
Armor- i would presume relatively low like 5 bash 5 slash 5 pierce… until it reaches an enraged threshold gaining quite a bit of armor. so kill it quickly for it would take probably 2-4 turns or so for it to get enraged while in combat.
Enrage- Gains a regen bonus, speed bonus, and armor.
So, Does this creature sound like it would be delightful. it would be relatively weak when not wallowing in blood and probably weaker than a standard bear though it could probably still hit quite hard just not very rapidly. perhaps half the attack speed of a bear.
Got any creature ideas feel free to post them below
