I'm just curious if anyone here has had spells (positive or negative) that have worked? There are so many sites on-line that offer spells for just about anything (usually at exorbitant costs). From my research, most of them have been scams. Has anyone here successfully delved into spellcasting?

Hello .  I am known as self-practice summoner .
It's not the Wiccan coven circle casting known as
animal friendship .,. it's Deific and modern Drago
Deind summoning after Green Kin casting so the:
Earth Shake known as Pana.t earthquake will not
be a problem at local system one , Neptune Row:
Jupiter Saturn Uranus and Sedna with astrolomy:
on the altar I keep to finish 100 system planetary
stones known as the Sylvan Planet Deity Altar . .
I am known to cast invisible lightening to bring ~
rain and strength casting , not pana.t shake so I:
may be peaceful with orbital promise and accord
to begin Medio~n Promise with Pantheon Deific .
I am not a spellbook caster , and I am bardic@!!

Depending on what you think a spell is, I think it is quite easy to weave a 'spell' that will work, but you have to believe in it 100%, have good intent and then also not very high expectations, add in some Law of Attraction and Manifestation and you can quite simply cause things to happen or create the situation you want.

But most websites are scam artists there for the money. If you know the situation and want to change something then you can use positive thought, nut freewill will  always overcome any pressure

Magic can be real .  Most magic is invisible .
Alchemy can be real though modern will be
the problem with pollution affecting alchem,
{y} as the Elixer of Life is not credible tho :
magic like invisible lightening and summon*
can be fully proper with modern " practice "
as we are not a magical world so we are uh
not the world of fantasy to be magically the
way spell~practice will say fireballs and the
sense of shape changing will be spellbooks:
Lore and Fantasy want this with imagin{ing}
though we don't have this power , . so when
we begin actual magic [my opinion not then
practice nor spell book though agility with a sense of intellect]  ~  we may offer the way it's real if not "selling something"

Most of the spells I do work. You have to believe in the spell, totally forget about it and not tell anyone that you have cast it.
