How can I use link_to in application_helper

I'm trying to parse some text and link certain strings that come from various models and is headed to a couple of different views. I though application_helper.rb was the right place to put this. (Still a rookie at figuring out where best to code things).

application_helper.rb

def link_buffs(text)
    Buff.all.each do |b|
      text = text.gsub('[' + b.name + ']',link_to('[' + b.name + ']', b, class: b.name + '-buff buff')).to_s
    end
    return text
  end

sample buff data 

buff.id:integer
buff.name = 'Poison'

sample text Places a 5% [Poison] debuff

And in the views, I'm calling link_buffs(string).html_safe in a few different places. But it appears to be silently failing and all I can figure out right now is that link_to isn't available in the helper.

So the question is how do I make link_to available in the helper or should I be putting this code somewhere else?

You should be able to do: ActionController::Base.helpers.link_to()

There are other answers to this question: create a link_to in controller
