Dialogue
From Mass Effect Wiki
Dialogue in Mass Effect differs from BioWare's previous titles. Instead of the traditional dialogue choices, which show you every word of your response verbatim, you are presented with paraphrases of your available dialogue options on a "conversation wheel". For example, one choice may appear as "Don't try to study me," while the actual spoken line is "I'm not some artifact you can take back to your lab, doctor."
The conversation wheel was designed to be intuitive. The left side of the wheel is normally reserved for Charm and Intimidate options (see below); occasionally an "Investigate" option is given in the middle, which allows Shepard to ask about multiple topics. The right side of the wheel is divided into three sections. Dialogue options that progress the conversation directly onward are located on the centre segment. Paragon responses--generally more conciliatory or inquisitive--are on the top segment, while Renegade responses--often more confrontational--are on the bottom segment.
Characters can also be influenced by the use of Charm or Intimidate. In the conversation wheel, Charm responses are blue while Intimidate responses are red. Use of those skills is affected by Commander Shepard's morality; if insufficient ranks in Charm or Intimidate have been unlocked, the options are greyed out. The harder a character is to persuade, the more ranks in the respective skills are needed.
Dialogue choices impact how others react to Shepard, the rewards for completing quests, possible discounts from merchants, romance paths and, most importantly, the commander's morality. It is also possible to defuse tense situations without violence, or actually provoke it.
[edit] Charm
Charm is used in dialogue to persuade people with compliments, clever diplomacy or a pleasant demeanor. Using Charm often encourages people to be more forthcoming or even willingly give extra rewards for assignments. In some cases Charm can defuse tense situations and resolve them peacefully.
Paragon points increase the available ranks in Charm; you also get extra Charm points from becoming a Spectre. As you obtain more Charm points, additional dialogue options will become available and you can unlock the 'Store Discount' which gives lower prices when buying from merchants.
Using Charm to resolve an apparently impossible situation can unlock the 'Charismatic' achievement.
[edit] Intimidate
Intimidate is used in dialogue to browbeat people with coercion, insults or threats. Using Intimidate can frighten or threaten individuals into cooperating or handing over extra rewards for assignments.
Renegade points influence Intimidate and affect its advancement. You also get extra Intimidate points from becoming a Spectre. As you obtain more Intimidate points, additional dialogue options will become available. Maxing out this ability will also unlock 'Motivated Buyer'--this increases the yield (amount of credits earned) by selling items to merchants (i.e. they give you a better deal because they're afraid of you).
Again, using Intimidate to resolve an apparently impossible situation can unlock the 'Charismatic' achievement.
[edit] Known Dialogue Issues
- There are certain NPC's (Non Player Character) that upon trying to initiate a conversation with them, or choosing a certain dialog option, the game cannot start the conversation or the an action as part of the conversation. This issue has been addressed in patch 1.02.
- Skip Dialog and Select Answer are both mapped to the space-bar, which can very easily result in also choosing dialog options by accident.
